30X47X11 MM 81106M 평면 스러스트 원통형 롤러 베어링(황동 케이지 포함)

그만큼 81106 thrust roller bearing is designed to withstand extreme unidirectional axial (thrust) loads in demanding applications. Ideal for heavy machinery such as crane hooks, vertical pumps, gearboxes, and injection molding machines.

Bearing Type: Single-direction cylindrical thrust roller bearing (ISO Type 81100 시리즈).

Key Dimensions (mm):

Shaft Washer Bore (d): 30 mm
Housing Washer Outside Diameter (D): 47 mm
Total Height (T): 11 mm

Cage Design: Utilizes a robust, precision-machined brass cage (designation suffix ‘M’ if applicable) or a pressed steel cage. The cage effectively spaces and guides the cylindrical rollers, ensuring even load distribution and smooth operation.

재료 & Construction: high-carbon chrome steel. The surfaces are precision-ground and lapped to minimize friction and ensure optimal contact.

Precision & 정리: Manufactured to standard tolerance classes (Normal class, P0). Available with standard axial internal clearance; modified clearances can be specified for applications with specific preload or thermal expansion requirements.

제품개요

그만큼 81106 thrust roller bearing features a robust structural design and is equipped with precise cylindrical rollers, which can provide outstanding load-bearing capacity, high rigidity 그리고 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 내구성, smooth operation and a longer service life in high-pressure conditions.

주요 특징:

Exceptional Unidirectional Axial Load Capacity
그만큼 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.
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.
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.
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.
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.
Industrial Machinery: 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.
