Skip to content special bearing is a bearing specifically engineered to operate under unique or demanding conditions where standard bearing designs cannot meet performance requirements. These bearings are customized in terms of structure, materials, precision grade, lubrication system, sealing design, or dimensional configuration to address specialized operating environments such as extreme temperatures, heavy loads, high speeds, corrosive media, vacuum conditions, or limited installation space. Typical characteristics of special bearings include application-specific design, enhanced durability, superior load capacity, improved resistance to environmental factors, and optimized performance for particular industrial equipment, ensuring reliable operation and extended service life in critical or non-standard applications.
Strong engineering design capability for non-standard bearings
Advanced CNC machining and precision grinding equipment
Strict quality control and material traceability
Flexible OEM and private label manufacturing services
Extensive experience serving diverse industrial sectors
Through our custom engineering expertise and advanced manufacturing capabilities, we deliver bearing solutions that help customers improve equipment reliability, operational efficiency, and long-term cost performance. We have customized the following types of bearings for our clients.
Bearing No:
6201 OR N662ZC3Z4 SRLS
OR: bearings with O-rings
Two rubber(material: NBR) O-rings are mounted on the outer ring of the bearing；Creep is prevented by limiting the amount of clearance between the outer ring and housing
We have carried out special heat treatment on the bearing steel to ensure that the bearing size does not undergo permanent deformation and the bearing hardness does not change. At the same time, we also use fluorine grease to ensure that the bearings have a longer lifetime when used in high-temperature environments.
Bearing No
6201N662ZC3Z4S15 SRLS
S15：high temperature resistant bearing
There are currently three specifications available
S15：Maximum operating temperature of 150 ℃
S18：Maximum operating temperature of 180 ℃
S20：Maximum operating temperature of 200 ℃
Bearings used in water pumps, marine equipment, chemical machinery, food and pharmaceutical equipment, and offshore engineering require extremely high corrosion resistance and sealing performance. Ordinary bearings often lack the materials and sealing properties to meet these requirements. Therefore, we have implemented special treatments to improve the materials and sealing performance of our bearings to meet the specific application needs.
Material:
Stainless steel 420, 440, 304, 316
Rust prevention salt spray test: The test is conducted using a 5% sodium chloride spray solution, and the salt spray test result is passed for more than 96 hours.
Sealing performance: Double or triple lip seals, and tightly controlled sealing clearances, bearing can realistically achieve is equivalent to IP69K protection.
Bearings used in industrial and humanoid robots have become a popular area for custom bearings in recent years, and VKUKEN is one of the earliest bearing design manufacturers to participate in custom robot manufacturing. They have customized thin-walled slewing bearings for the waist, ball bearings for actuators, angular contact ball bearings for the feet, roller and ball bearings for actuators, and tapered roller bearings for the knees, among others.
Material:
GCr15 / AISI 52100,440C、
420,Silicon Nitride (Si₃N₄)
The bearing requirements we address:
Very low rotational friction and torque
Minimal runout and high rotational accuracy
Stable and consistent motion control
Reduced overall robot weight
More compact mechanical joint designs
Low vibration operation
Quiet running performance
The above are just a few examples of our custom bearing projects. In addition, we have also customized stainless steel bearings, ceramic bearings, hybrid ceramic bearings, mounted bearings, slewing bearings, non-standard size bearings, etc. for food processing equipment, outdoor industrial equipment, OEM machinery projects, industrial robots, and the automotive industry.
