Cross Roller Bearing Type
Model RU (Integrated Inner/Outer Ring Type)
Since holes are drilled for mounting, the need for a presser fl ange and a housing is eliminated. Also, owing to the integrated inner/outer ring type stryucture with washer, there is almost no effect from installation on performance, allowing stable rotational accuracy and torque to be obtained. Can be used for both outer and inner ring rotation.
Model RB (Separable Outer Ring Type for Inner Ring Rotation)
Cross-Roller Ring basic type, with a separable outer ring, and an inner ring integrated with the main body.It is used in locations where the rotational accuracy of the inner ring is required. It is used, for example, in the swivel portions of index tables of machine tools.
Model RE (Two-piece Inner Ring Type for Outer Ring Rotation)
Main dimensions are the same as model RB. This model is used in locations where the rotational accuracy of the outer ring is required.
Model RA (Separable Outer Ring Type for Inner Ring Rotation)
A compact type similar to model RB with the thinnest possible inner and outer rings. Optimal for locations requiring a
light-weight and compact design such as the swivel portions of robots and manipulators.

Medical Device
With the comprehensive development of scientific and technological strength, the social economyu has been improved faster, and the medical equipment has also been comprehensively improved.
Mining & construction machinery
Mining machinery and heavy construction machinery industry uses a range of different types of highly specialized mobile machinery.
. The places where mining machinery and construction machinery are active are mostly mining sites such as mountains and deserts
that are far away from ordinary human life. These heavy machinery work in the harshest environments and require continuous
low-friction work without reducing load capacity and minimum. assembly and adjustment time. Solving the bearing heating problem caused by the large exciting force, high vibration frequency and continuous operation of vibratory rollers for users has becomethe focus of the work.

Transportation vehicle
Metric and inch needle roller bearings have various structural types, mainly including open drawn cup needle roller bearings,
closed drawn cup needle roller bearings, needle roller bearings with inner ring and needle roller bearings without inner ring/without inner ring Cage needle roller bearings, caged and cageless needle roller bearings. Widely used in automobiles, motorcycles, mopeds, power tools, textiles, agricultural machinery, printing machinery, construction machinery, automatic
instruments and other fields.

Automatic machinery
Industrial robot bearings mainly include two categories: one is thin-walled bearings, and the other is crossed cylindrical roller
bearings. In addition, there are harmonic reducer bearings, linear roller bearings, spherical plain bearings, etc. Bearings with
good performance have large bearing capacity, good rigidity, high rotation precision and easy installation.

FAQ
Q.How do deep groove ball bearings (DGBBs) differ from single-row angular contact ball bearings?
A:DGBBs can withstand axial loads in both directions, whereas single-row angular contact ball bearings can only accommodate axial loads in one direction.
Q.What are the differences between open, sealed, and shielded deep groove ball bearings?
A:Seals and guards protect bearings and help with lubrication. Sealed bearings offer the highest protection, followed by shielded bearings, with open bearings having no additional protection. Sealed bearings are marked with 2RS, shielded bearings with Z or ZZ, no sealed call Open pattern.
Q.How do you guarantee your quality?
Q.How do you guarantee your quality?
A: 1 year warranty, ISO certificated.
Q. Do you supply installation service?
A: Yes, we have after-sale service team who can provide installation service, the trip cost should be borne by buyer.
Q.How much discount is subject to increasing my order size?
A: Order amount: Over $10,000 - $500 off. Over $1000 - $50 off. Over $500 $25 off.
Q.How to become our agent?
A: After 1-2 years of cooperation and mutual inspection, the agent can be authorized based on performance.
Q.What are radial loads and axial loads?
A:Loads are classified based on their direction relative to the shaft. Radial loads are those perpendicular to the shaft, while axial loads are parallel to it. This distinction helps in understanding how forces act onmechanical systems like machinery and structures.
