Steel Adjustable COMBINED ROLLER BEARING, Packaging Type : Box

frequently asked questions - combined roller bearings

1. How do we mount the bearings? the stub axle on the bearings is made from st52 which is a weldable steel. The best method is to drill a hole to locate the stub diameter marked 'd' in the drawings and to weld from behind. The 45 chamfer or weld gusset allows the weld to be kept flat if you need to use that area for rolling another bearing over. You do not have to disassemble the bearing to weld into position, just keep the torch or arc away from the hardened steel radial roller and axial roller.

2. How do you lubricate the bearing? all but the smallest size of the standard combined range have a threaded lube hole and hex-headed plug to allow the insertion of a grease nipple. All lube holes are m6 tapped. Remove the plug to allow for the insertion of a nipple. If the nipple cannot be left in place for operational reasons, re-insert the plug. Use a good bearing grease e.g shell alvania 3 or esso beacon 3. Nipples are not supplied but the holes are standard metric threads. The standard bearings are pre-lubricated and can be run without any further lubrication. The adjustable types are not re-lubricable but are pre-lubricated for life.
