TRW Bearing FAQS

QHow to INSTALLATION BEARING?

AA hammer or other mechanism that induces a shock load on the bearing should never be used. The corner of the housing bore should have a radius or chamfer that has a smooth transition to the housing bore. The bearing should be aligned to the bore and a constant steady force applied to seat the bearing. A tool, which pilots on the bearing bore and which applies load to the outer ring face, is recommended.

QWhat is the material of Insert bearing?

AInsert bearing may be 17-4PH,15-5PH, 440C, 52100 chrome plated, Inconel® 718, Cobalt, Aluminum, Beryllium Copper,PH13-8Mo

QWhat is material of RBC Split Ball Bearings?

AVarious materials are use.Races: 17-4PH, 15-5PH,Inconel® 718, aluminum(requires PTFE liner or hard coat), titanium (requires PTFE liner or hard coat).Balls: Copper alloys, titanium,aluminum, 440C, PH13-8Mo,15-5PH, 17-4PH, cobalt alloys.

QHow to Mount bearing?

ADuring handling, the rings and roller complement of spherical roller bearings may be axially displaced from their normal position. This is especially likely where the bearings are mounted with the shaft or housing in the vertical position: The roller complement, together with the inner or outer ring, will move downward and result in no more clearance. When the bearing rings expand or contract as a result of an interference fit, preload is likely to result. Therefore, wherever possible: Mount spherical roller bearings with the shaft or housing in the horizontal position. Rotate the inner or outer ring to align the rollers during mounting. Where this is not feasible, use a bearing handling tool or other device to keep the bearing components arranged centrally.
