620 Series - Crimping Tool
Tooling for Crimping 1970 Series Bearings into a 2.5” Dia. x 11 - 14 gauge tube

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 GenII® Semi-Precision, 1000 lb GenII® 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 Requirements
  • 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.
Tube Hardness
  • 70 Rb or softer (BHN 125; 10 mm Ball, 3000 kg)
Tube Preparation Required
  • 2.5” O.D. tubes with 12, 13, or 14ga 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 11ga 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.

This tooling is recommended for use with FRANTZ bearings only.
