Product Description

THK Cross Roller Ring Bearing SX011814 SX011814-A

Structure and character
Cross roller bearing,because of its vertical arrangement of cylindrical roller with a 90°V groove
through the separate spacers in the deep groove rolling surface. This design allows just one
bearing to receive loads in all directions including radial, axial and moment load.
At the same time, cross roller bearing is a light weight, compact type with thinnest possible inner
and outer rings, especially for the thinnest, with high rigidity. it is optimal for applications such as
joints and swiveling units of industrial robots. swiveling tables of machining centers.rotary units of
manipulators.precision rotary tables,medical equipment, measuring instruments and IC manufacturing machines.
Excellent rotation accuracy
The spacers fitting among cross arranged rollers prevents rollers from skewing and the rotation
torque from increasing due to friction between rollers. The spaces keeps rollers in their proper
position,thereby preventing them from skewing. It does nor cause unilateral contact of roller or
locked rollers.Since the inner and outer rings are designed to be separable, the bearing clearance
can be adjusted, in addition, a preload can be applied. These features enable accurate rotation.
Easy Handling
The inner and outer rings.Which are separable,are secured to the body after being installed with
rollers and spacers. Therefore, it is easy to handle the rings when installing the Cross Roller Bearing.

FAQ1: What are the features of SX011814 cross roller bearings?

The SX011814 cross roller bearing is a compact, high-rigidity bearing known for supporting high loads from all directions.
Its main features are:
Crossed Roller Arrangement: Rollers are arranged at $90^\circ$ angles to handle simultaneous radial, axial, and moment loads.Thin-Walled Design: The SX series has a very thin inner and outer ring, contributing to a compact and space-saving profile.
Integral Construction: The outer ring is usually split, but once assembled, the unit is highly rigid, offering a large diameter in a small overall space.

FAQ2: SX vs RB cross roller bearings difference

The main difference lies in the design of the inner and outer rings:
RB Series (Standard): Has a split outer ring and a solid inner ring. This design is common and provides high accuracy.
SX Series (Compact): Has a split inner ring and a solid outer ring. This makes the SX series particularly suitable for applications where the inner ring needs to be mounted onto a shaft or mounting surface that is rotating or when the housing design requires a solid outer circumference. The SX series is also generally more compact.

FAQ3: Applications of the THK SX series in automation

The THK SX series is vital in automation due to its high precision and compact size.
Common applications include:
Industrial Robots: Used in the joints and articulation points where heavy, multi-directional loads must be supported with high accuracy.
Precision Rotary Tables: In CNC machining and inspection equipment.
Medical Equipment: In CT scanners and diagnostic machinery that require smooth, precise rotation.
Indexers and Turrets: For compact, high-speed positioning in automated assembly lines.
