Bearing Material: Chrome steel. Design Units: Metric. Series: 7200. Base Number: 7204. Part Number: 7204TDULP5. Unit Quantity: 2 Pcs.

Decoding the designation

7204 — ISO 72 light series angular contact ball bearing, 20 mm bore.

T — machined phenolic cage.

DU — duplex universally ground, so any two pieces close to the set preload in any arrangement.

L — light preload.

P5 — ISO tolerance class 5, ABEC 5.

What these specs mean in practice

Precision Class: ABEC 5 / P5. Bore, outside diameter and running accuracy are held to roughly half the standard tolerance band, which is what holds shaft position and keeps running vibration down at speed.

Cage Material: Phenolic. A machined fabric-base laminate cage is light and self-lubricating, which suits sustained high-speed running. The carton cross-designation carries the Fafnir CR code, which is the same phenolic construction.

Preload: L light. The light class is chosen where spindle speed and heat matter more than absolute axial stiffness. Internal Clearance is not applicable on a preloaded set.

Mounting data

Shaft seat 20 mm. Housing bore 47 mm. Ring width 14 mm each, 28 mm across the pair. The universally ground faces let the two pieces be arranged back-to-back, face-to-face or in tandem, with the ground offset setting the preload in each case.

Quantity and configuration

Unit Quantity: 2 Pcs. Arrangement / Configuration: Duplex universally ground set of two. Mounting Arrangement: Universally matchable back-to-back, face-to-face or tandem.

Interchange guidance

Cross-Reference 1: RHP 7204TDULP5. Cross-Reference 2: Timken 2M204WI CR DUL. The 20 x 47 x 14 mm envelope is the ISO 7204 size, so SKF 7204, FAG 7204 and NSK 7204 share the boundary dimensions. Those are related sizes rather than interchanges until the contact angle is matched: 15°, 25° and 40° bearings all exist on this envelope and they behave very differently in thrust and in speed.
