81109 Thrust Ball Bearing | M / TN Types Available

The 81109 thrust ball bearing is a high-precision single-direction thrust ball bearing optimized for pure axial load operation. Featuring compact size, high structural rigidity and low friction, it ensures accurate axial positioning and stable running for low and medium-speed industrial machinery. Offered in 81109M and 81109TN cage models, this bearing provides durable and cost-effective mechanical support for various transmission systems.

81109 M / TN Type Differences

81109M: Equipped with a solid machined brass cage with high rigidity, outstanding heat resistance and strong impact resistance. It runs stably with minimal wear during long-term continuous operation, ideal for heavy-load, high-temperature and harsh industrial working conditions.

81109TN: Features a lightweight nylon TN cage with a low friction coefficient and quiet rotation performance. It delivers excellent anti-fatigue properties and high cost performance, perfect for medium-speed, clean and stable working environments with standard axial load demands.

Material Introduction

Bearing Steel (GCr15): Standard 81109 thrust ball bearings adopt premium GCr15 high-carbon chromium bearing steel. Through professional heat treatment, raceways and steel balls achieve high hardness, superior wear resistance and stable fatigue resistance, supporting long-term precise and stable operation under continuous axial loads.

Stainless Steel (Optional): Custom stainless steel 81109 bearings provide reliable rust-proof, anti-oxidation and weak corrosion resistance. They adapt well to humid, dusty and sanitary working scenarios, preventing premature bearing failure and extending overall service life.

Product Features

Reliable single-direction pure axial load capacity. Precision axial positioning with low operating noise. Two cage designs fit diverse speed and load conditions. Excellent hardness and wear resistance extend service life. Compact structure saves installation space with great cost performance.

Application Scenarios

81109 thrust ball bearings are widely used in hydraulic systems, industrial gearboxes, ventilation fans, textile machinery, printing equipment and general mechanical transmissions. 81109M suits heavy-load and harsh working environments; 81109TN is ideal for medium-speed, low-noise and cost-sensitive equipment. Stainless steel versions apply to humid and sanitary industrial conditions.
