CM/CF Series Stainless Steel Rod End
CM and CF rod ends run a 440C stainless ball directly against a precision-machined 304 stainless race without a liner. This metal-to-metal joint handles high static loads and frequent impact loads without deformation. Requires routine grease lubrication. Housings in 304 stainless standard, with 316 and 17-4PH options.
Applications:
Ideal for heavy-duty, slow-oscillating industrial pivots that can be greased on schedule. Commonly specified for press linkages, agricultural arms, and industrial damper mechanisms subject to shock loading.
- Metal to Metal Race
- Two Piece Construction
- Grease Serviceable
- 316 and 17-4PH Body Options
