What these specs mean in practice

Per bearing: Dynamic Load Rating: 10,300 N. Static Load Rating: 4,250 N. Limiting Speed: 38,000 rpm grease; 60,000 rpm oil. Fatigue load limit, radial: 450 N.

Precision Class: ABEC 7 / P4. Cage Material: Phenolic. Cage Type: Machined. Lubricant: grease or oil. Operating temperature range: -30 °C to +100 °C.

A 15° contact angle carries more radial load and runs faster than a 25° execution of the same size. On a 20 mm bore that puts the oil-lubricated ceiling at 60,000 rpm. Series: B70. Base Number: B7004.

Mounting data

Preload per matched pair: light 51 N, medium 175 N, heavy 356 N. Universal grinding means the assembler selects the preload class by arrangement rather than by ordering a different part number.

Mounting Arrangement: Universal — the pair mounts back-to-back (O), face-to-face (X) or tandem. Internal Clearance: N/A; the set is preload-adjusted rather than clearance-set.

Quantity and configuration

Unit Quantity: 2 Pcs. One matched duplex set, ground and supplied as a pair.
