Manufactured to ISO 15 / ISO 492 / GB/T 292 / GB/T 307.1, H7000C Series Precision Spindle Angular Contact Ball Bearings are angular contact ball bearings supplied by Bushing Bearings. Every designation in the series is listed with its boundary dimensions; the interactive half-section drawing redraws itself for whichever size you select.
What Are H7000C Series Precision Spindle Angular Contact Ball Bearings?
H7000C Series Precision Spindle Angular Contact Ball Bearings are angular contact ball bearings defined by ISO 15 / ISO 492 / GB/T 292 / GB/T 307.1. They are selected by bearing designation and the dimensional characteristics shown below. Material, cage and sealing are specified separately from the designation and are covered further down this page.
Materials & Cage
Rings and balls are through-hardened GCr15 / 100Cr6 at 58 to 64 HRC. Because this bearing is preloaded rather than run with clearance, the cage matters more than usual: pressed steel for general duty, machined brass or phenolic for spindle speeds, PEEK where temperature and chemical exposure rule out phenolic. Hybrid ceramic balls are specified on high-speed spindles for their lower mass and therefore lower centrifugal load on the outer raceway.
H7000C Series Precision Spindle Angular Contact Ball Bearings are supplied to order. Pricing starts from approximately US$30.00 per piece for standard bore sizes in bearing steel, single bearings at normal preload; final pricing depends on size, material, finish and order quantity (MOQ applies). Submit your exact configuration with the quote form above.
Specifying the H7000C Series Precision Spindle Angular Contact Ball Bearings
If the shaft is already fixed, go straight to the size: 50 mm bore, 55 mm bore, 60 mm bore and 65 mm bore. Each of those pages repeats only the row that matters for that bore, with the fit and clearance notes underneath it.
Where the environment decides the specification rather than the load, the material pages are the ones to read: GCr15 Bearing Steel, Martensitic Stainless 440C and Silicon Nitride Si3N4. Each states what the grade survives, and what choosing it costs in load capacity or temperature range.
This bearing is forged, hardened, ground, superfinished and clearance-set in-house. The stages below are where its tolerance class, its internal clearance and its noise grade are actually decided.
01
Forging & turning
GCr15 bar and tube is cut, heated and forged into ring blanks, then turned to leave a uniform grinding allowance. Forging rather than machining from solid keeps the grain flow following the raceway, which is the surface that eventually fails.
Blank dimensions and grinding stock checked at set-up and per shift.
02
Heat treatment
Through-hardening brings GCr15 / 100Cr6 to 58–64 HRC; carburizing case-hardens 20CrMnTi where the section is heavy or the load is shock. Rings are then stabilized so they hold size in service rather than growing in the housing.
Core and surface hardness per lot; retained austenite and dimensional stability to the ordered temperature class.
03
Raceway grinding
Faces, bore, outer diameter and raceway are ground in sequence on separate machines. This is where the tolerance class is created: P0, P6, P5 or P4 is a grinding outcome, not a sorting outcome.
Bore and outer diameter deviation, raceway roundness and face runout measured to ISO 492 on every setup.
04
Honing & superfinishing
The ground raceway is honed to remove the grinding lay and bring surface roughness down to a fraction of a micrometre. Raceway finish is what decides whether a lubricant film forms, and therefore what decides bearing life far more than the load rating alone.
Surface roughness Ra and waviness measured per lot.

Frequently Asked Questions
What standard governs H7000C Series Precision Spindle Angular Contact Ball Bearings, and how are they mounted?
H7000C Series Precision Spindle Angular Contact Ball Bearings are manufactured to ISO 15 / ISO 492 / GB/T 292 / GB/T 307.1, which fixes the boundary dimensions on this page. They are mounted with an interference fit on the shaft and a transition or clearance fit in the housing, chosen from the load case and which ring rotates.
Which sizes of H7000C Series Precision Spindle Angular Contact Ball Bearings does Bushing Bearings supply?
The table on this page lists 21 sizes for H7000C Series Precision Spindle Angular Contact Ball Bearings, ranging from H7000C to H7020C. Sizes outside the table can be quoted on request.
In which materials are H7000C Series Precision Spindle Angular Contact Ball Bearings supplied?
H7000C Series Precision Spindle Angular Contact Ball Bearings are supplied in through-hardened GCr15 / 100Cr6, with machined brass, phenolic or PEEK cages for spindle service and silicon nitride balls on high-speed spindles. Material is only part of the specification: state the internal clearance group (or preload class), the seal or shield type and the cage material alongside the designation, because all three change the part you receive.
What shaft and housing tolerances suit H7000C Series Precision Spindle Angular Contact Ball Bearings?
The smallest bore on this page is 10 mm. With a rotating inner ring under normal load the shaft is normally machined to k5 or m6 and the housing to H7 or J7, so the inner ring is an interference fit and the outer ring can move axially to take up thermal growth. Reverse the fits when it is the outer ring that rotates. Check the figure against your own load case before machining.
