Single Row Ball Slewing Bearing

Single Row Ball Slewing Bearing – Precision Engineered for Reliable Rotation

When your equipment requires smooth and reliable rotation under combined loads, Single Row Ball Slewing Bearing provides the performance you need. This type of bearing utilizes a single row of steel balls, housed in precisely ground raceways, to simultaneously withstand axial, radial, and overturning moment loads. Whether you are involved in construction machinery, material handling systems, or rotating platforms, this design offers a compact and cost-effective solution. Hengguan Bearing manufactures a wide range of products with diameters from 50 mm to 5000 mm, all designed and manufactured according to international standards and your specific application requirements.

Product Details

Our product features a simple yet robust structure. Components include inner and outer rings, precision steel balls, spacers or cages, and a highly effective sealing system. The four-point contact between the steel balls and raceways ensures even load distribution across the bearing. This design allows the bearing to withstand axial forces, overturning moments, and moderate radial loads within a compact cross-sectional size.

The bearing rings are made of 50Mn or 42CrMo alloy steel and heat-treated for optimal hardness and toughness. The rolling elements are made of GCr15 bearing steel and precision ground to extremely tight tolerances. The seals are made of oil-resistant nitrile rubber (NBR), effectively preventing contaminants from entering and maintaining lubrication.

We offer a wide range of sizes, with inner diameters ranging from 50 mm to over 5000 mm, and cross-sectional heights typically between 30 mm and 150 mm. This flexibility allows you to select the appropriate bearing for various applications, from light-duty rotary tables to medium-sized construction machinery.

Technical Specifications

Features and Benefits

Four-Point Contact Design

The ball-to-raceway contact geometry distributes forces across four points, enabling the Single Row Ball Slewing Bearing to handle combined loads with a single row of balls. This reduces assembly height compared to multi-row designs.

Compact Cross-Section

You get significant stack capacity in a thin profile, sparing space and decreasing in general hardware weight. This is especially profitable in portable apparatus where weight imperatives matter.

Cost-Effective Solution

Simpler development than double-row or crossed roller heading implies lower fabricating costs without compromising execution for numerous common applications.

Flexible Estimate Range

From little pivoting stages to huge development hardware, our generation capabilities cover a wide breadth run to coordinate your gear specifications.

Integrated Adapt Options

We machine outside or inside gears straightforwardly onto the bearing rings, killing partitioned equip components and disentangling your drivetrain design.

Proven Fabric Selection

High-strength combination steels stand up to misshapening beneath stack, whereas accuracy bearing steel balls guarantee smooth operation and amplified benefit life.

Applications

Construction Machinery

Truck-mounted cranes, portable cranes, scaled down excavators, and boom lifts depend on these heading for cab turn and boom situating. The compact plan fits tight establishment spaces whereas taking care of energetic loads amid operation.

Material Dealing with Equipment

Stackers, slewing transports, and rotational tables utilize these heading for ceaseless revolution beneath direct loads. The fixed plan ensures against tidy and flotsam and jetsam common in distribution center environments.

Industrial Platforms

Rotating work stages, mechanical arms, and ordering tables advantage from the smooth revolution and situating precision these heading provide.

Communication Equipment

Radar frameworks and obsequious dishes require exact, smooth turn for following and situating. The moo contact and exact operation make these heading appropriate for such applications.

Medical Equipment

CT scanners and other pivoting restorative gadgets utilize these heading where smooth, calm operation is essential.

Installation Guide

Pre-Installation Checks

Verify that mounting surfaces are level, clean, and free from burrs. Check that mounting jolt gaps adjust appropriately with bearing gaps. Affirm that your chosen jolts meet the indicated review requirements.

Mounting Surface Preparation

Ensure mounting surfaces have fitting levelness (ordinarily inside 0.05 mm per 100 mm distance across). Expel any paint, rust, or flotsam and jetsam that may avoid legitimate seating.

Bearing Placement

Position the bearing on the mounting surface, adjusting all jolt gaps. Utilize arrangement pins if given to guarantee concentric placement.

Bolt Installation

Install mounting jolts taking after a star design. Fix slowly in different passes to guarantee indeed weight dissemination. Apply the torque indicated in the item documentation—typically based on jolt estimate and grade.

Gear Work Adjustment

If utilizing an outside drive pinion, alter the backfire to the suggested clearance (regularly 0.2-0.4 mm). Confirm contact design over the tooth confront width.

Lubrication

Fill oil through the given grease ports until new oil shows up at the seals. Utilize the prescribed oil sort based on your working temperature range.

Exhibition

We attend many famous international exhibitions such as Shanghai International Maritime Exhibition,Mining World Russia, bauma China, CTT Russia, etc

Partners

Your trust, we cherish in heart all times and will reciprocate that trust with unwavering quality.

Packaging & shipping

Your goods are unique, and their journey should be flawless. Therefore, we offer professional and customized packaging services. Our experienced team will evaluate your goods' characteristics, transportation route, and environmental requirements to recommend the most secure solution, such as: wooden crate packaging, sturdy frame packaging, or composite reinforced packaging (wooden crate + iron frame).

Maintenance and Care

Regular Lubrication

Relubricate at interims based on working conditions—typically each 100-300 working hours for ceaseless revolution applications. More visit oil may be required in sullied environments.

Inspection Schedule

Check mounting jolt torque after the to begin with 100 working hours and intermittently from that point. Assess seals for harm or wear. Screen for bizarre clamor or vibration that might demonstrate defilement or wear.

Raceway Condition

If available, occasionally review raceways for signs of erosion, defilement, or wear. Address any issues expeditiously to avoid quickened damage.

Operating Stack Monitoring

Avoid surpassing the bearing's evaluated stack capacity. Over-burdening quickens wear and can lead to untimely failure.

Storage

If putting away unused orientation, keep them in a dry, clean environment. Apply a rust preventive coating if long-term capacity is anticipated.

FAQ

Q: What's the distinction between single push and twofold push ball slewing bearings?

A: Single push heading have one push of balls with four-point contact, advertising a more compact plan. Twofold push heading utilize two lines of balls, giving higher stack capacity but requiring more establishment space.

Q: Can you give orientation with extraordinary surface treatments?

A: Yes. We offer surface medicines counting phosphating, galvanizing, and specialized coatings for destructive situations. Examine your prerequisites with our specialized team.

Q: How do I select the right bearing estimate for my application?

A: Give us with your stack necessities (pivotal, spiral, and minute loads), turn speed, mounting space imperatives, and working environment. Our engineers will suggest fitting sizing.

Q: What oil ought to I use?

A: We regularly prescribe lithium-based oil with EP added substances for common applications. Particular proposals depend on your working temperature and speed.

Q: Do you offer testing some time recently shipment?

A: Yes. We perform dimensional confirmation, hardness testing, and utilitarian testing some time recently shipment. Extra testing can be organized based on your requirements.

Q: What lead time ought to I anticipate for custom bearings?

A: Standard sizes ordinarily transport inside 2-3 weeks. Custom plans require 4-8 weeks depending on complexity and current generation plan.
