Die Set Components

Die set components are packaged as a set to assure tolerance compatibility.

Ball Bearing Bushings, Retainers, and Guide Posts

JT&M's ball bearing components are precisely matched for full contact pre-load operation. Guide pins are made of case hardened steel and are precision ground. Ball retainers are made from gold anodized aluminum and hold a 25 millionth tolerance class chrome alloy ball. Each ball is held captive with four stakes. Ball bearing bushings are made of hardened steel and are ground and honed to exact tolerance. Longer post lengths are available upon request. Maximum stroke length is three inches.

2. Apply bushing mount to die set hole.
3. Insert bushing into die set and allow 24-hour cure time.
