The R10 Series (R10 Open, R10Z/ZZ, R10RS/2RS) is a standard inch-sized deep groove ball bearing measuring 5/8" (ID) × 1-3/8" (OD) × 11/32" (Width), equivalent to 15.875 × 34.925 × 8.731 mm. Built for high accuracy and low noise, it supports both radial and moderate axial loads. We supply global B2B buyers with customizable material options (GCr15, Carbon Steel, or Stainless Steel), flexible sealing configurations, and comprehensive OEM/ODM services—contact us for fast dispatch within 3–15 days.
Deep groove ball bearings are the most widely used bearing class globally due to their simple, reliable, and versatile design. The R10 Inch Series Bearing is specifically engineered for markets and equipment that utilize imperial (inch) measurements. It is primarily designed to handle radial loads but can also support certain axial (thrust) loads in both directions. By increasing the radial internal clearance, this bearing can mimic angular contact functions to handle even larger axial forces.

Item | Specification |
Bearing Series | R10 (Inch Series) |
Dimensions (Inch) | 5/8" × 1-3/8" × 11/32" |
Dimensions (Metric) | 15.875 mm × 34.925 mm × 8.731 mm |
Dynamic Load Rating | ≈ 2.91 kN / 654 lbf |
Static Load Rating | ≈ 4.60 kN / 1034 lbf |
Precision Grades | P0 (Standard), P6, P5, P4 |
Quality Standard | ISO9001:2000 |
We manufacture the R10 series to meet the exact demands of your operating environment:
Material options: Choose from standard Carbon Steel for light duties, GCr15 Chrome Steel for high load and long life, or Stainless Steel for corrosion resistance in wet environments.
Open (R10): No seals; designed for continuously oil-lubricated systems.
Shielded (R10Z / R10ZZ): Equipped with one or two metal shields. Prevents dust entry while allowing high-speed, low-friction rotation.
Sealed (R10RS / R10-2RS): Features contact rubber seals. Provides excellent protection against moisture and fine contaminants, making the bearing splash-proof.
The R10 bearing delivers high accuracy, low running noise, and low weight, making it a critical component across multiple industries:
HVAC systems, pumps, and compressors.
Small electric motors and machine tools.
Auto parts, tractors, and agricultural machinery.
Conveyor systems and textile equipment.
We cater specifically to industrial distributors and equipment manufacturers. We offer comprehensive OEM and ODM services, allowing you to source bearings under a neutral brand or customized with your own company logo.
Packaging: Industrial tube/bulk packaging or custom individual boxes according to buyer requirements.
Lead Time: Fast fulfillment, with normal ready goods and stock dispatched within 3–15 days.
Payment Terms: Flexible options including 100% T/T, 30% T/T advance (with balance against B/L or L/C at sight), PayPal, and Western Union.
Q1: What does the "R" stand for in the R10 bearing?
A: The "R" prefix designates that this is an imperial (inch-sized) series deep groove ball bearing, as opposed to the standard metric 6000 series.
Q2: Are the R10ZZ and R10-2RS bearings pre-lubricated?
A: Yes, both the shielded (ZZ) and sealed (2RS) versions come pre-lubricated from the factory with the correct amount of high-quality grease and are sealed for the lifetime of the bearing, reducing maintenance costs.
Q3: Can I get this bearing in stainless steel?
A: Yes. For applications exposed to moisture or corrosive elements, we can manufacture the R10 series using stainless steel. Please specify this requirement in your inquiry.
Q4: Do you supply other inch-series bearings?
A: Absolutely. As a comprehensive manufacturer, we provide a full range of small, miniature, standard, and non-standard inch and metric ball bearings. Send us your complete purchasing list for a combined quotation.
