30X47X11 MM 81106M 真鍮製ケージ付き平面スラスト円筒ころ軸受

製品概要

The 81106 thrust roller bearing features a robust structural design and is equipped with precise cylindrical rollers, which can provide outstanding load-bearing capacity, 高剛性 そして reliable performance in environments with low to medium rotational speeds. The load-bearing capacity of the thrust roller bearing is higher than that of the thrust ball bearing, ensuring 耐久性, smooth operation and a longer service life in high-pressure conditions.

主な特長:

1. Exceptional Unidirectional Axial Load Capacity
   The 81106 thrust roller bearing is engineered specifically to handle very high axial loads. Its design, featuring large cylindrical rollers with line contact on the raceways, provides a much higher load rating compared to thrust ball bearings of a similar footprint.

2. High Rigidity and Minimal Axial Deformation
   Under heavy axial load, the bearing exhibits minimal elastic deformation (axial deflection), ensuring precise axial positioning and stability of the supported component.

3. Durability in Harsh Conditions
   The hardened steel construction provides excellent resistance to wear, shock loads, and impact, leading to a long and reliable service life even in tough industrial environments.

4. Compact Design for High Load Density
   It offers an excellent ratio of load-carrying capacity to its envelope dimensions, making it a space-efficient solution for applications with severe space constraints.

5. Suitable for Low/Moderate Speeds
   While optimized for load over extreme speed, it performs reliably in applications with moderate rotational speeds, especially when adequately lubricated.

Primary Application Scenarios

• Material Handling & Lifting Equipment: Crane hooks, swing bearings, and the axial support in vertical gearboxes for winches.

• 産業機械: Heavy vertical pumps, valve actuators, injection molding machine clamps, and press rams.

• Power Transmission: As an axial locator in helical gearboxes and worm gear reducers to counteract axial thrust from the gears.

• Automotive & Transportation: In heavy vehicle clutches, heavy-duty jacks, and steering column thrust applications.

• Agricultural & Construction Equipment: Pivot points and axial supports in heavy implements and machinery.
