Danley 6-2511-82 Ball Bearing Cage 25mm ID 110mm L Linear Slide Bushing

Danley 6-2511-82 Ball Bearing Cage 25mm ID 110mm L Linear Slide Bushing

The Danley 6-2511-82 is a ball bearing cage designed for use in Type II and Type III ball bearing bushing assemblies in linear slide systems. The cage provides the precision ball-retention structure that allows a shaft or guide post to move smoothly along a linear axis with minimal friction and consistent wear distribution.

Applications

Ball bearing cages like the Danley 6-2511-82 are core components of linear slide and linear motion systems used throughout industrial automation, precision machine tools, die and mold equipment, and mechanical assembly machinery. Danley Engineering is a long-established American manufacturer of precision industrial components, and their ball bearing bushing assemblies are standard in die sets, punch press tooling, and general-purpose linear guides. The spiral ball arrangement in this cage distributes the contact load evenly across multiple balls at different angular positions, which reduces the tendency of a worn groove or track to develop in the shaft — a key feature for maintaining dimensional accuracy and component longevity over extended use cycles. These cages are used wherever a guide post or shaft must move repeatedly in a straight line under controlled preload, including press tooling, fixture guides, robotic end-effectors, and precision jig assemblies.
