LamGlide™ Bushings - New!

The LamGlide™ bushing is a premium bushing designed for the most demanding applications. Its unique patented liner provides superior wear resistance over bronze and steel. The LamGlide™ bushing is maintenance free and operates burr and wear filing free. It can be used anywhere linear or vertical motion is required.

LamGlide™ bushings have outstanding physical, mechanical and chemical properties that include lightweight material, self-aligning, dimensional stability, tolerance to edge loading, and resistance to chemical attack. resistance.

Stress Test Comparison
LamGlide™ vs other bushings

Description: Various bushing makes were field tested on the same Lift Mechanism within a Progressive Die. Operators did not lubricate the bushings.
Bushing Types Field Test Life Cycle
NO LUBRICATION after installation
Hardened Steel Drill Bushing * failure after 10,000-20,000 cycles
Bronze Self-Lubricating Bushing * failure after 50,000-60,000 cycles
LamGlide™   greater than 1.8 million cycles
(no failure yet)

*Note - with regular lubrication & maintenance, life of bushing is significantly increased.

Conclusion: LamGlide™ Bushings are ideal for high-stress production environments where operators do not lubricate the bushings at regular intervals or where lubricant contamination, debris or byproducts are undesirable.
