Frequently Asked Questions
Q: What rail system is the TBR20UU linear slider bearing block compatible with?
A: The TBR20UU Linear Slider Bearing Block is designed to work with TBR20 linear guide rails that have a 20mm bore/shaft diameter. It is commonly used in CNC machines, 3D printers, and industrial automation setups that use this standard rail size.
Q: What material is the TBR20UU bearing block made from?
A: The bearing block housing is constructed from aluminum alloy, which provides a strong yet lightweight structure with excellent abrasion resistance and corrosion resistance thanks to the surface oxidation (anodizing) treatment.
Q: Does this linear slider bearing block include dust protection?
A: Yes. The TBR20UU bearing block incorporates a dust-prevention design that helps seal out contaminants, protecting the internal ball bearing mechanism and prolonging the service life of the entire linear guide system.
Q: How many bearing blocks are included in one order?
A: Each order includes 1 × TBR20UU Linear Slider Bearing Block. No additional hardware or rail is included.
