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)
Toleransi diameter roller dikawal dalam ± 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%
Boleh menahan beban radial sehingga 5000n
Rintangan impak yang sangat baik, sesuai untuk keadaan beban berat
2. Selection and installation guide
Selection points:
Select roller arrangement according to load type (radial/axial/torque)
Menurut keperluan kelajuan berjalan menentukan kaedah pelinciran (pelinciran minyak/pelinciran minyak)
Consider environmental factors (corrosiveness/cleanliness) to select materials
Choose the appropriate grade according to the accuracy requirements
Langkah berjaga -jaga pemasangan:
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
Keluarkan kekotoran dari permukaan kereta api secara berkala
Check the looseness of fasteners
Lubrication management:
Grease lubrication: Replenish grease every 3000 hours
Oil lubrication: Establish a centralized lubrication system
Pelinciran gas minyak disyorkan untuk keadaan berkelajuan tinggi
Penilaian Kehidupan:
Pantau perubahan bunyi operasi
Regularly check the wear of the rollers
Consider replacement when the operating accuracy drops by 20%
