Crossed Roller Bearings' Installation and Maintenance
How to install Crossed Roller Bearings? It's different with common bearings' installation, and need to pay attention to a lot details. This article will teach you step by step.
Lubrication
Bearings have been filled with complex lithium grease before delivery, so they can be immediately put into application under normal working conditions, without extra lubrication during operating. At the initial stage of running,
bearings' friction torque will increase temporarily, and will become stable along with running, after grease evenly coated the raceway and rollers.
Installation Steps
1. Before installation, please clean bearing bracket, shaft, or other components, make sure there is no burrs or
rough edge.
2. Place the bearing into the bearing bracket and main shaft, to match the design clearance, keep the bearing
horizontal and insert the bearing into the bearing bracket or shaft. If it is hard to install, use a rubber hammer
to slightly hit every part of the bearing, so that the bearing can be inserted into the bearing bracket or shaft easily.
Pay close attention to the hitting force as the bearing could be damaged if the force is too large. Afterwards,
the matching status of bearing and basic face can be examined by checking the noise.
3. Install the mounting disc: Place the mounting disc onto the bearing and align the screw holes. Screw all the bolts in the holes first and follow the order as shown in below diagram when tightening bolts in diagonally opposite
sequence. Do not tighten bolts randomly.
Cautions
- Bearings have been adjusted to preload and filled with lubricant before delivery, users shall not disassemble or attempt to clean bearings before installation. Please contact our after-sales staff for any problem during installation or application.
- Normal operating temperature of the bearing is -20℃~+80℃, please contact our technicians if it's over this temperature range.
- Bearing components material can choose aluminium alloy or cast iron.
- If you can not find suitable dimensions in the form, please contact our technicians, we can produce customized type.
