This tool is designed to crimp a 1970 series bearing into a 2.5” diameter tube, securely locking the bearing into the tube. The bearing must be assembled loosely, or by press fit, into the tube prior to using this tool.

• High quality Tool Steel


• Nest for roller assembly, to permit HANDS-FREE press closure


• Attaches to your adapter plate with three 5/16-18 screws on a 2.875” bolt circle, or can be clamped by the flange


• Will also work with 300 lb GEN II® semi-precision, 620 lb GEN II® semi-precision, and various GENSTAR® precision bearings by changing the center piloting knock-out sleeve


• Built by, and in stock at Frantz® Manufacturing Company

• Press must have a method of consistently stopping its stroke to prevent “dog-boning” of the roller ends


• Must be capable of enough pressure to buckle a 2.5” - 11ga tube, but have a relief valve to limit that pressure to approximately 19 tons.

• 70 Rb or softer (BHN 125; 10 mm Ball, 3000 kg)

• 2.5” O.D. tubes with 12, 13, or 14 ga wall thickness require only a squarely cut end. Bearings can be loosely assembled into the tube. Load carrying capability will vary, depending upon the fit up.


• 2.5” O.D. tubes with 11 ga or thicker wall will need to be reamed to accept a slip or press fit of the bearing. The bearing must be inserted into the tube BEFORE this tool is used.


• A Frantz® Manufacturing engineer can evaluate your “worst case” cut-off, and press a bearing into one of your tube samples for your inspection.
