Military Application Story

Installed in rifle gun mount assemblies

Harsh desert conditions work to restrict linear motion performance in rifle gun mounts installed into light infantry vehicles. Micro diameter dust particles permeated through wear seals and seized all travel for the bronze bushings outfitted to absorb gun recoil. Extreme temperatures, heavy vibration and lack of consistent lubrication also caused significant problems for sustainable system operation.

Components:

Simplicity Linear Plain Bearings

Retrofit or OEM:

Retrofit

Problem:

Ultra-fine sand penetrates through seals and restricts smooth motion while gun recoil forces and high shock loads damage the shafting, resulting in the overall failure of the gun mount assembly.

Solution:

Simplicity bearings excelled in absorbing high shock forces, even under the added stress of combatting sand, dirt, heat and lack of lubrication.

The PBC Linear Solution

PBC Linear’s Simplicity® plain bearings push contaminants—sand, dirt and dust—off the shafting to ensure smooth, accurate and long-term operation of the gun mount system. Simplicity® bearings contain no rolling elements and glide on a proprietary Teflon liner; providing even disbursement of forces all along the bearings to better absorb load, vibration and gun recoil. Simplicity® bearings also self-lubricate, making them an attractive product for field applications where preventative maintenance is limited.

Results / ROI

Once installed, the Simplicity linear bearings provided reliable absorption of recoil forces for the gun mount assembly in environments where competing linear bearing technologies failed. Without additional grease or oil, Simplicity’s self-lubricating liner further detracted dirt, dust and other debris from corrupting the system. The liner also eliminated the need for periodic lubrication and maintenance checks; thereby ensuring clean and smooth linear motion and extending product life.
