Deep Groove Ball Bearings
The general-purpose bearing: radial and light thrust in one part, ABEC 5–7.
The bearing most designs start with, because it takes radial and a useful amount of thrust in one part. Where the load is modest and the speed is normal, it is the cheapest correct answer.

What drives the price of this part
Derived from the callouts on this page. Where a driver is not on the drawing, it is not on this list.
- Part size
- Bore range at Ø3–Ø200 mm decides which machine the part lands on and how many setups it needs. Size is the driver buyers most often leave out of a first enquiry, and it is the one that changes the quote fastest.
- Material
- The first material listed, Bearing Steel 52100 (100Cr6), rates 4/10 on our machinability scale at 60–66 HRC hardened · 183–217 HB annealed. On this shop's scale a harder alloy means slower passes and more tool changes, and that is cycle time the quote has to carry.
- Order size
- Minimum order is 25 pieces, where setup and tooling are amortised across the batch and per-part cost settles around cycle time and material. Below that quantity the same part costs more per piece, not less.
See how cycle time is calculated in the machining time calculator and what else moves a price in the cost driver reference.
How these parts are inspected
Matched to the callouts above and the instruments actually on the floor.
- Coordinate measuring machine (Zeiss CONTURA G2, two machines, GR&R 8.4% on the critical feature)
- Dimensional report against the drawing, with a 100% check on critical features rather than a sample
- Certificate of conformance and the mill certificate with every shipment
- Bore gauges and an optical comparator for hole position and edge form
The full equipment list, with counts, is on the capability page; the inspection sequence is on quality and inspection.
Questions buyers ask
- C3 clearance or standard?
- C3 when the bearing runs hot or is a press fit on both rings, because the fit itself consumes clearance. Standard (CN) for a normal shaft and housing at moderate temperature.
