BR2 series products
BR2 (DX) boundary self-lubricating bushing
BR2Y metal base boundary lubrication bushing
BR2Y boundary lubrication lead-free bearing is improved on the basis of BR2. Its performance is the same as that of BR2, but its surface does not contain lead. Its application field can be extended to the field with environmental requirements. At present, the product has been used in imported textile equipment, piston pump swing parts, automobile joystick parts and other medium load, medium speed, grease lubrication occasions.
