Single-row bearings carrying combined radial and axial load at a contact angle. Supplied singly or matched in pairs (DB / DF / DT) for spindle, pump and high-speed duty.
| Series | Typical use | Options |
|---|---|---|
| 7200 / 7300 | Machine-tool spindles, pumps, compressors | 15° / 25° / 40° contact angle, P0–P6 |
| Paired sets | Duplex arrangements for axial rigidity | DB · DF · DT, preloaded |
Two rows of symmetrical rollers on a common spherical raceway — high radial capacity with self-alignment for heavy, shock-loaded and misaligned applications.
| Series | Typical use | Options |
|---|---|---|
| 22200 / 22300 | Mining, aggregates, vibrating screens | Cylindrical / tapered bore, C2–C4 |
| 23000 / 24000 | Heavy gearboxes, paper and steel machinery | Brass or steel cage |
| 21300 | Conveyors, fans, agricultural equipment | Sealed variants on request |
Separable cone and cup design carrying combined radial and single-direction axial load. Standard for wheel axles, agricultural implements and gearboxes.
| Series | d × D (mm) | Typical use |
|---|---|---|
| 30204 – 30212 | 20×47 → 60×110 | Wheel hubs, axles, small gearboxes |
| 30304 – 30310 | 20×52 → 50×110 | Heavier axial load, truck and trailer axles |
| 320 / 322 / 323 | Wide range | On request |
Separable rings allow independent mounting of inner and outer ring; the line contact design gives high radial capacity and excellent high-speed behaviour.
| Series | Design | Typical use |
|---|---|---|
| NU 2xx / 3xx | Free floating inner ring | Electric motors, generators |
| NJ / NUP | One-direction axial location | Gearboxes, machine tools |
| N | Plain radial | High-speed spindles |
Wheel hub units, tensioner and clutch release bearings for passenger cars, trucks and agricultural tractors — a core strength of the Chengli factory.
| Product | Description | Fitment |
|---|---|---|
| DAC series | Sealed wheel hub ball bearings, 2RS sealed | Passenger cars, light commercial |
| Hub units | Gen.1 / Gen.2 / Gen.3 to drawing | OEM replacement market |
| Tensioner & clutch | Belt tensioner and clutch release bearings | Engine and driveline |
Single and double direction bearings for pure axial load in screw jacks, cranes, valves, pumps and vertical shaft assemblies.
| Series | Design | Typical use |
|---|---|---|
| 51100 / 51200 | Single direction | Machine tools, jacks, couplings |
| 51300 / 51400 | Single direction, heavier section | Cranes, presses, vertical pumps |
| 52xxx / 53xxx | Double direction | Reversing axial load |
Wide inner ring insert bearings with grey cast iron / thermoplastic housings — the fastest way to fit and replace a bearing on conveyors and farm machinery.
| Series | Housing types | Typical use |
|---|---|---|
| UC200 / UC300 | UCP pillow block · UCF flange · UCT take-up | Conveyors, fans, harvesters |
| SA / UK | Spherical OD inserts, set screw or adapter | Agricultural equipment |
Where shaft deflection or housing misalignment cannot be avoided, these designs keep running smoothly by self-aligning on a spherical raceway.
| Series | Type | Typical use |
|---|---|---|
| 21300 / 22200 | Self-aligning roller | Long-span shafts, vibrating machinery |
| 1200 / 1300 | Self-aligning ball | Light-duty drives, textile machinery |
| 2200 | Self-aligning ball, wide | Conveyors, fans |
Maximum load capacity in the smallest radial section — ideal where space and weight are constrained.
| Series | Design | Typical use |
|---|---|---|
| HK / BK | Drawn cup, caged or full complement | Gearboxes, universal joints |
| NA / RNA | Machined ring with ribs | Rockers, pivots, pumps |
| Cam followers | Stud type | Conveyor guides, cam mechanisms |
Self-lubricating, corrosion-resistant linear motion components for food, chemical and clean environments.
| Series | Design | Typical use |

For customers who require a specific global make, we source and supply imported-brand bearings alongside our own range — one supplier, one shipment, one invoice.
Send a drawing, a sample or a photo of the old part. We quote on material, heat treatment, clearance, seal type and packaging — and produce under the same quality system as our standard range.
