W Series Line Track Rollers Bearing: High-precision linear motion solution

1. Product Overview and Features

W Series Line Track Rollers Bearing is a mechanical element designed for high-precision linear motion. It uses an optimized roller structure to achieve smooth, low-friction linear motion on the guide rail system. This series of bearings has the following outstanding features:

Precision roller design:

Adopt high-precision bearing steel rollers with special hardening treatment on the surface (hardness HRC58-62)

Roller diameter tolerance is controlled within ±0.005mm

Optimized profile design ensures optimal contact with the guide rail

Low friction performance:

Rolling friction coefficient is as low as 0.001-0.003

Compared with the traditional slider structure, the running resistance is reduced by more than 60%

High-speed movement (up to 5m/s) can be achieved

High-rigidity structure:

Integrated bearing seat design, rigidity increased by 30%

Can withstand radial loads up to 5000N

Excellent impact resistance, suitable for heavy-load conditions

2. Selection and installation guide

Selection points:

Select roller arrangement according to load type (radial/axial/torque)

According to the running speed requirements Determine the lubrication method (grease lubrication/oil lubrication)

Consider environmental factors (corrosiveness/cleanliness) to select materials

Choose the appropriate grade according to the accuracy requirements

Installation precautions:

The flatness of the guide rail installation reference surface must be ≤0.02mm/m

The bearing seat fixing bolts must be tightened step by step in diagonal order

The preload force should be adjusted to make the running resistance uniform

Fully lubricated before initial operation

3. Maintenance recommendations

Daily maintenance:

Check the lubrication condition every 500 hours

Remove impurities from the guide rail surface regularly

Check the looseness of fasteners

Lubrication management:

Grease lubrication: Replenish grease every 3000 hours

Oil lubrication: Establish a centralized lubrication system

Oil-gas lubrication is recommended for high-speed conditions

Life assessment:

Monitor changes in operating noise

Regularly check the wear of the rollers

Consider replacement when the operating accuracy drops by 20%
