Trusted across industries for reliable performance
Ball bearings are widely used in automotive wheel hubs, transmissions, and engine accessories, delivering high-speed operation and long service life.
Electric motors, pumps, compressors, and drive systems rely heavily on ball bearings for reliable and efficient operation.
Tractors, harvesters, and irrigation equipment require durable ball bearings that withstand harsh field conditions.
Deep groove ball bearings are the most common bearing type in motors, providing low-noise, high-speed smooth operation.
Precision ball bearings in diagnostic devices and surgical instruments demand ultra-high accuracy and minimal vibration.
Ball bearings in aircraft engines and flight control systems must endure extreme temperatures and high-speed loads.

Ball bearings come in several types including deep groove ball bearings (the most common), angular contact ball bearings (for combined loads), self-aligning ball bearings (for shaft misalignment), thrust ball bearings (for axial loads), and thin section bearings (for space-constrained applications). JMP Bearings offers over 26,000 models across all types.
Select a ball bearing based on load type (radial, axial, or combined), operating speed, required precision grade, operating temperature, and available mounting space. Use our Bearing Finder tool to filter by bore diameter, outer diameter, width, seal type, and cage material.
Open bearings have no seals, allowing maximum speed but requiring regular lubrication. Sealed bearings (2RS) have rubber seals on both sides, keeping lubricant in and contaminants out. Shielded bearings (ZZ) use metal shields for moderate protection at higher speeds.
JMP Bearings supplies ball bearings in ABEC-1 through ABEC-9 (ISO P0 through P2) precision grades. Standard applications typically use ABEC-1 (P0), while high-speed spindle and precision instrument applications require ABEC-7 (P4) or ABEC-9 (P2).
Most ball bearings use chrome steel (GCr15/52100) for rings and balls, offering excellent hardness and wear resistance. Stainless steel (AISI 440C/ SUS440C) is used for corrosion resistance. Hybrid bearings combine ceramic (Si3N4) balls with steel rings for higher speed and lower friction.
Load ratings include static load rating (Co) and dynamic load rating (C). Static load rating indicates the maximum load the bearing can withstand while stationary without permanent deformation. Dynamic load rating determines bearing life under rotating conditions, calculated using the L10 life formula.
Yes, JMP Bearings provides custom ball bearing solutions including non-standard dimensions, special materials, custom cage designs, and application-specific lubricants. Contact our engineering team with your requirements for a custom quote.
Ball bearing part numbers typically follow a standard format: the first digits indicate the bore diameter (e.g., 6205 = 25mm bore, where 05 x 5 = 25), the series number indicates the bearing type and size class (e.g., 62 = deep groove, light series), and suffixes denote seals (2RS), shields (ZZ), clearance (C3), and cage material.
JMP Bearings is a professional ball bearing manufacturer and supplier based in Ningbo, China. With years of experience in precision bearing production, we serve global distributors, wholesalers, and OEM clients across more than 50 countries. Our in-house manufacturing capabilities and strict quality control ensure consistent product performance at competitive pricing.
We offer a comprehensive range of ball bearings to meet diverse industrial requirements. Our product line includes deep groove ball bearings for general-purpose applications, angular contact ball bearings for combined load conditions, self-aligning ball bearings for misalignment compensation, and thrust ball bearings for axial load support. Standard and custom sizes are available, with inner diameters ranging from 3mm to 200mm.
All JMP ball bearings are manufactured from high-carbon chromium steel (GCr15 / AISI 52100), heat-treated for optimal hardness and wear resistance. Precision grades range from ABEC-1 for standard industrial use to ABEC-7 for high-speed and high-accuracy applications. Grease and oil lubrication options, along with sealed (ZZ) and open configurations, are available across our full catalog.
Our precision bearings are widely used in electric motors, automotive wheel hubs and transmissions, industrial gearboxes, pumps, agricultural equipment, and conveyor systems. Whether you need high-volume production runs or small-batch orders, JMP Bearings provides reliable sourcing with short lead times.
