010.30.630 Slewing Bearing – High-Performance Non-Geared Four-Point Contact Ball Bearing

Luoyang Heng Guan Bearing Technology brings you the 010.30.630 Slewing Bearing, a precision-engineered non-geared rotary solution designed for demanding industrial applications. This 732x528x80mm single-row four-point contact ball bearing delivers reliable multi-directional load support without integral gearing—ideal when you need external drive systems. With a robust 1,870 KN load capacity and compact 80mm height, this model offers exceptional space efficiency. Manufactured from premium 50Mn/42CrMo alloy steel with raceway hardness of 55-62 HRC, it's backed by our ISO9001-certified facility in Luoyang—China's bearing hub. With over 30 years of expertise and products exported to 50+ countries, we guarantee precision grades from P0 to P5 and full technical support including CAD drawings.

Technical Specifications

Product Features & Engineering Advantages

1) Four-Point Contact Design for Multi-Directional Load Handling

The four-point contact ball structure enables the 010.30.630 specifications to simultaneously manage axial, radial, and tilting moment loads within a single compact unit. This eliminates the need for separate thrust and radial bearing assemblies, simplifying your machine design while reducing installation space by up to 30%.

2) No Gear Configuration – Perfect for External Drive Solutions

Smooth, toothless 010.30.630 slewing bearings differ from internally geared ones. This makes it excellent for belt, hydraulic, and external motor integration. Gear-free rotation decreases vibration, noise, and contaminant sealing, making it essential in medical imaging, wastewater treatment, and precise automation.

3) Premium Alloy Steel & Induction Hardening

Precision induction quenching produces 55-62 HRC raceway hardness in each bearing made of high-strength 50Mn or 42CrMo alloy steel. This heat treatment hardens the surface for wear resistance and maintains a shock-absorbing core, increasing service life under cyclic loads.

4) Rigorous Quality Control & Testing

Each unit undergoes ultrasonic fault detection, coordinate measuring machine dimensional tolerance verification, and rotational testing. Our comprehensive traceability system follows each bearing from raw material procurement to delivery, assuring production batch quality.

Applications

A) Construction Excavator – Excavators & Mobile Cranes

For 20-ton excavators and truck-mounted cranes, the 010.30.630 (732mm OD, 528mm ID) provides strong swing support. Boom-down drilling and asymmetric lifting are supported by 1,870 KN. Jobsite muck, dust, and debris are blocked by the double rubber seal.

B) Offshore & Marine Equipment

Saltwater corrosion destroys pedestal cranes on oil rigs and ship-mounted cargo handlers. We provide marine-grade anti-corrosion coating and salt fog-resistant lubricants for the 010.30.630 model. Maintenance in isolated offshore sites where repair downtime costs thousands per hour is easier with the non-geared design.

C) Mining & Drilling Rigs

In continuous-duty mining shovels or rotary drilling rigs, the 010.30.630 load capacity supports heavy bucket payloads and drilling torque. The bearing's 24 bolt holes (18mm diameter) ensure secure mounting even under shock loads from rock breakage. Our 42CrMo material option provides extra strength for these extreme environments.

D) Wind Power & Rail Transit

Wind turbine pitch control systems benefit from the compact 80mm height and smooth rotation of this non-geared bearing. In rail maintenance equipment and turntable applications, the 010.30.630 bolt hole dimensions match standard mounting patterns, enabling straightforward OEM replacements without custom fabrication.

Interchange Reference

The 010.30.630 model often serves as a direct replacement for equivalent four-point contact ball bearings in the 630mm raceway diameter class from European manufacturers. When sourcing alternatives, verify:

· Raceway center diameter (630mm)

· Mounting hole patterns (24×φ18 on 696mm/564mm circles)

· Height clearance (80mm)

· Load rating compatibility (≥1,870 KN)

We provide 1:1 interchange verification based on your existing bearing or equipment model number. Contact Us with dimensional data or photos for cross-reference confirmation.

OEM & Custom Manufacturing Capabilities

In addition to catalogue goods, Heng Guan Bearing offers specific customisation to meet your needs:

· Our engineers arrive to your plant with precise instruments to reverse-engineer old or undocumented bearings, excellent for situations without original designs.

· Our load-optimized designs use finite element analysis (FEA) to adjust raceway shape, ball amount, and material grades to fit your duty cycle.

· Special coatings and treatments include zinc-nickel plating, Teflon linings, and vacuum heat treatment for hostile chemical or temperature conditions.

· · CNC vertical lathes and gear hobbing machines (up to 10,000mm diameter capacity) are used to create matching gear rings, flanges, couplings, and Shafts.

010.30.630 typical production takes 3-4 weeks. Depending on intricacy, custom projects take 5-8 weeks.

FAQ

Q1: What is the load capacity of the 010.30.630?

A: The basic load rating is 1,870 KN, suitable for medium to heavy-duty rotating applications. For static load calculations or specific duty cycle analysis, our engineers provide free load assessment based on your operating conditions.

Q2: Does the 010.30.630 have internal or external gear teeth?

A: This is a No Gear (toothless) model, designed for external drive mechanisms like pinion-rack systems, hydraulic motors, or friction drives. If you need geared variants, we offer internal/external gear options with the same base dimensions.

Q3: What are the bolt hole dimensions for the 010.30.630?

A: 24 holes of φ18mm diameter on both inner and outer rings. Outer bolt circle: 696mm; Inner bolt circle: 564mm. This pattern accommodates M16 mounting bolts with standard washers.

Q4: What material is the 010.30.630 made of?

A: Rings are forged from 50Mn or 42CrMo alloy steel (customer selectable). Balls are high-carbon chromium bearing steel (GCr15). All materials comply with ISO 683 standards and are RoHS certified.

Q5: Can I get a CAD drawing for the 010.30.630?

A: Yes. We provide 2D technical drawings (PDF/DWG) with full dimensions including the 010.30.630 technical drawing showing bolt patterns, raceway profiles, and tolerances. 3D models (STEP/IGES) available upon request after order confirmation.

Q6: What is the delivery time?

A: Standard precision (P0 grade): 3-4 weeks from order confirmation.
