INA Roller Bearing Open End Type 25 mm Inside Diameter 42 mm Outside Diameter 11 mm Race Width 81105-TV

INA 81105-TV Roller Bearing is a high-quality mechanical component characterized by a 25 mm inside diameter and 42 mm outside diameter, with an 11 mm race width. This bearing is designed with an open end type, allowing straightforward inspection and re-lubrication to maintain optimal performance over time. Rated for a limiting speed of 8,600 rpm, it is tailored for medium-speed rotating assemblies where reliable radial load capacity is essential.

This Roller Bearing features a static load capacity of 76 kN and a dynamic load rating of 33.5 kN, delivering sustained support under high preload conditions while enhancing the operational fatigue life of mechanical systems. The parallel bore design accommodates interference or transition shaft fits, ensuring versatility in installation and applications.

The INA 81105-TV bearing is ideally suited for industrial sectors including agricultural driveline components that require frequent service access, light industrial gearboxes, centrifugal pumps, and conveyor idlers in material handling systems. Its design supports electric motor auxiliary bearings with parallel bores, reflecting broad utility across mechanical and manufacturing applications.

Key features of this bearing include its open end design facilitating visual checks and lubrication, compact axial space usage due to its 11 mm race width, and high-speed capability with an 8,600 rpm limiting speed. The component complies with industry standards but does not carry specific approvals or certifications.

This bearing provides a static load capacity of 76 kN, supporting mechanical systems under standstill without deformation. The dynamic load rating of 33.5 kN enhances durability under operational fatigue. Its limiting speed of 8,600 rpm makes it suitable for moderate-speed drives.

The open end bearing type enables direct re-lubrication and inspection during maintenance. Its parallel bore supports various shaft fit types depending on mounting practice. Compact race width of 11 mm optimizes axial space in assemblies.

Ideal for agricultural, industrial gearbox, pump, conveyor, and electric motor auxiliary bearing applications.
