Features and Benefits

Crossed Roller Design

The 90° roller arrangement provides equal load distribution in all directions. You eliminate the need for paired Cross Roller Ring Bearings, saving installation space and reducing assembly complexity.

Tall Rigidity

Integrated raceway development and ideal roller contact points convey prevalent firmness. Your gear keeps up positional precision indeed beneath shifting stack conditions.

Compact Footprint

By combining hub and outspread stack taking care of in one unit, you decrease in general framework measurements and weight—critical for automated arms and rotational ordering tables.

Split Ring Options

Our part internal or external ring arrangements rearrange establishment on strong Shafts or lodgings. You spare gathering time and diminish upkeep downtime.

Multi-Grade Precision

From standard P0 to ultra-precise P4, you select the exactness level that matches your application—whether it's a common mechanical turntable or a accuracy estimation instrument.

Customization Capability

We plan and make non-standard heading based on your working conditions. Send us your ancient bearing or application parameters; our engineers will create a custom fitted solution.

Applications

Industrial Robotics

Joint actuators and rotating bases advantage from the compact estimate and multi-directional stack capacity. You accomplish smooth, exact movement control with negligible backlash.

CNC Machine Tools

Rotary tables, ordering heads, and swivel units depend on cross roller rings for situating precision beneath cutting powers. You keep up tight resistances over long generation runs.

Medical Equipment

CT scanners, surgical robots, and demonstrative imaging gadgets utilize these orientation for noiseless operation and positional repeatability. Understanding security and symptomatic precision depend on this reliability.

Aerospace and Defense

Antenna positioners, radar turrets, and adherent components require lightweight, high-stiffness heading. You meet rigid weight budgets without compromising performance.

Semiconductor Manufacturing

Wafer taking care of robots and assessment stages request ultra-clean, low-particle-generation heading. Our fixed variations ensure touchy forms from contamination.

Installation Guide

1.Pre-Installation Inspection

Clean mounting surfaces completely. Check for burrs, scratches, or erosion that seem influence fit accuracy.

2.Mounting Surface Preparation

Ensure levelness and perpendicularity of mating surfaces. Utilize precision-ground spacers if vital to accomplish legitimate alignment.

3.Bearing Positioning

For split-ring plans, collect parts with arrangement pins some time recently fixing. Maintain a strategic distance from cross-threading jolts amid assembly.

4.Bolt Fixing Sequence

Tighten mounting jolts in a star design to disseminate clamping constrain equitably. Utilize a calibrated torque torque taking after our detail sheets.

5.Lubrication Application

Apply prescribed oil or oil some time recently beginning operation. Fill oil ports to 70-80% capacity to dodge over-pressurization.

6.Initial Run-In

Operate at 30-50% evaluated stack for the to begin with few hours. Screen temperature and vibration to affirm appropriate installation.

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

Lubrication Schedule

Re-grease each 500-1,000 working hours, or yearly, whichever comes to begin with. High-speed or high-load applications may require shorter intervals.

Inspection Routine

Check for unusual clamor, vibration, or temperature rise month to month. Early discovery avoids disastrous disappointment and impromptu downtime.

Seal Integrity

Inspect seals quarterly for wear or harm. Supplant instantly to avoid defilement and grease loss.

Storage Conditions

Store orientation in a dry, temperature-controlled environment. Wrap in VCI paper if long-term capacity surpasses six months.

FAQ

Q: What stack bearings can items handle?

A: They bolster pivotal, outspread, and minute loads at the same time in a single bearing unit.
