50 Sets of RB Crossed Roller Bearings Shipped to the USA

BY Bearings recently completed a shipment of 50 sets of RB30025 crossed roller bearings to a customer in the United States. The bearings are intended for use in DD motor turntables and precision rotary tables, where accurate rotational movement and structural rigidity are essential.

This shipment reflects the continued demand for precision bearing components in industrial applications that require compact bearing arrangements, reliable rotational support, and consistent performance under operating loads.

Shipment Overview 

This shipment involved 50 sets of RB30025 crossed roller bearings for a customer in the United States. The bearings were specified for DD motor turntable and precision rotary table applications.

The key shipment details are summarized below.

Item	Shipment Details
Product	Crossed Roller Bearings
Model	RB30025
BY Bearings Product Series	BRB Series (RB-Compatible)
Quantity	50 Sets
Destination	USA
Application	DD Motor Turntables, Precision Rotary Tables

The order was prepared and packaged for export as part of BY Bearings' international supply activities. For overseas shipments, careful handling and suitable packaging are important considerations to help protect bearing surfaces and maintain product identification during transportation.

This shipment represents another example of BY Bearings supplying precision crossed roller bearing products to international industrial equipment customers.

Product Overview

The RB30025 bearings supplied in this shipment belong to the RB-type crossed roller bearing category. BY Bearings offers the BRB series crossed roller bearings, a product range designed to be interchangeable with mainstream RB series crossed roller bearings.

The BRB series features an integrated inner ring and a split outer ring. Its cylindrical rollers are arranged alternately at 90-degree angles, allowing a single bearing to accommodate radial loads, axial loads, and overturning moments simultaneously.

The integrated inner ring design makes the BRB series particularly suitable for applications requiring high rotational accuracy of the inner ring. The split outer ring allows for precise adjustment of internal clearance or the application of preload to eliminate mechanical play.

With their combined load capacity, compact design, and high rigidity, BRB series bearings are suitable for industrial robot joints, CNC rotary tables, precision indexing heads, DD motor turntables, and other precision rotating mechanisms.

For equipment manufacturers seeking alternatives to RB-type crossed roller bearings, the BRB series provides compatible product options. Engineers should confirm the corresponding model dimensions, mounting interfaces, and precision requirements when selecting a replacement bearing.

How Crossed Roller Bearings Support DD Motor and Precision Rotary Table Applications

DD motor turntables and precision rotary tables are used in equipment where accurate angular positioning and stable rotational movement are important. These applications place specific demands on the bearing system.

Zero backlash: Any internal clearance or lost motion in the bearing translates directly into positioning error. Preloaded crossed roller bearings eliminate internal play, ensuring that motion is transmitted without lost motion or impact.

High rigidity: The bearing must resist deflection under load to maintain positioning accuracy. The line contact between cylindrical rollers and raceways provides approximately three times the rigidity of ball bearings of equivalent size.

Combined load support: DD motor turntables and rotary table bearings applications may experience axial loads, radial loads, and tilting moments simultaneously. The crossed roller arrangement allows a single bearing to support all three load types within a compact assembly.

Compact design: The integrated structure of crossed roller bearings reduces the number of components required and simplifies the rotary axis design. This is particularly valuable in DD motor applications where space is limited and the bearing must integrate directly with the motor rotor.

Smooth rotation: The precision spacers between rollers prevent skewing and reduce friction, supporting smooth motion and consistent torque characteristics. This is important for applications requiring precise speed control or low-speed positioning.

These characteristics make crossed roller bearings a suitable choice for DD motor turntables and precision rotary tables where compact construction, high rigidity, and accurate rotational movement are required.
