Bison-Bial TULEJA 1751-4-1 PTPA — mechanical bushing/liner

TULEJA 1751-4-1 PTPA by Bison-Bial is a mechanical bushing designed to provide a replaceable bearing surface for shafts, pins and rotating elements in industrial machinery. Manufactured as a precision sleeve, this bushing reduces wear between mating parts, helps maintain alignment and simplifies maintenance by allowing quick replacement of a worn bearing surface without replacing the entire assembly.

Advantages

The bushing offers a hardened and dimensionally stable contact surface that extends component life and reduces downtime. Its cylindrical sleeve design ensures consistent radial support and helps maintain concentricity of shafts and pins under load. As a replaceable component, it lowers repair costs and allows targeted maintenance of assemblies exposed to abrasion and friction.

Suitable for

• Shaft support and alignment in rotating assemblies
• Wear protection for housings, flanges and pin joints
• Repair and refurbishment of industrial machines and agricultural equipment
• Applications requiring a replaceable bearing surface or sleeve

Key specifications

• Product type: mechanical bushing / sleeve
• Form factor: cylindrical liner designed for press-fit or slip-fit installation
• Primary function: bearing surface to reduce wear and maintain alignment
• Typical materials: engineered metal suitable for bearing and wear applications
• Intended use environment: industrial and mechanical assemblies subjected to radial loads and friction

How to use

Select the bushing with dimensions matching the shaft and housing tolerances. Clean mating surfaces before installation and check for burrs or corrosion. Install the sleeve by press-fitting or sliding into the housing bore, taking care to align it concentrically. After installation, verify shaft clearance and rotation to ensure smooth operation. Replace the bushing when visual wear, increased play, or noise indicate loss of bearing performance.

Usage recommendations

Use appropriate installation tools to avoid deformation of the sleeve and follow machine manufacturer tolerances for interference or clearance fits. Regular inspection and lubrication of the mating shaft, where applicable, will prolong service life. Store spare bushings in a dry, clean environment to prevent surface contamination prior to installation.
