LM & LMF - Bronze bearings acc. to swedish standard
Products in the LM-group
- LM - Plain bearings acc. to swedish standard SS 776
- LMF - Flanged bearings acc. to swedish standard SS 778
Design
Inside dia tolerance: F7
Ouside dia tolerance: p6
Grease grooves: Are made with so called plain groove or spriral groove. Spiral grooves are standard grooves on SS 778 (flanged bearings). Can be made upon request on SS 776 (plain bearing).
Chamfer: Inner and outer chamfer with 45°.

Low till medium-big loads. Few sensitive to to edge pressure. Unhardened mating material possible |
* By continous operating and/or higher sliding speed, the above given datas will be heavily reduced.
Other alloys
LM /SS 776 and LMF /SS 778 can be produced in other bronze alloys. The mechanical values can be increased. LM & LMF in other alloys is however no standard product and therefore not stocked by us.
