Bull Dog Linear Bearings

Product catalog summary

Product Overview: The Bull Dog Linear/Rotary Bearings™ feature a super tough glass epoxy shell with a Minuteman Self Lubricating™ liner, designed for high impact, shock, and vibration resistance. These bearings offer high load capacity and can withstand incredible compression loads, outperforming competing composite materials.

Key Features:

Self-Lubricating Design: Provides maintenance-free operation, eliminating the need for costly lubrication systems.
Low Coefficient of Friction: Reduces wear and extends operating life, with coefficients as low as 0.05 in dry applications and <0.009 in lubricated environments.
Temperature Resistant: Operates effectively from cryogenic levels to 300°F (149°C).
Dimensionally Stable: Negligible absorption rates ensure near-zero swell in fluids.
Flexible Material Design: Suitable for various fitting methods including press fit, freeze fit, epoxy bonding, and mechanical retention.
Low Weight/High Strength: Offers a compact strength-to-weight ratio.

Advantages: The bearings are self-lubricating, lightweight, non-metallic, chemically inert, electrically insulated, and impact resistant.

Applications: Suitable for military vehicles, gun mounts, marine applications, washdown equipment, packaging machinery, outdoor environments, and construction equipment.

Specifications:

Part numbers range from LFG-8 to LFG-16, with varying dimensions and tolerances for ID, OD, housing bore, and bearing length.
Performance metrics include PSI of 5000, PV of 30,000, and SFM of 400.
Compatible with RC60 steel, 300 series stainless, and ceramic coated aluminum shafting.

Additional Information: LM76 is a major supplier of linear shafting and shaft assemblies, offering products like RC60 hardened steel shafting, 440C stainless, 300 series stainless, and ceramic coated aluminum.
