Cage Material: Phenolic. Cage Type: Machined, outer-ring land-riding. Preload: Light. Mounting Arrangement: Single universal. Bore Type: Straight. Closure Type: Open. Number Of Rows: 1. Rolling Elements: Balls. Bearing Material: High carbon chrome bearing steel, SAE 52100. Series: 7000. Country of Origin: United States.

Decoding the designation

7005 gives the ISO series 10 envelope at a 25 mm bore. E is the contact angle code in the RHP scheme and fixes it at 25°. SUL is the grouping and preload: SU for a single universally ground bearing, L for light preload. P6 is the precision grade, ABEC 3. The carton also carries the Fafnir cross 2M9105WI-DUL on the same envelope.

What these specs mean in practice

Dynamic Load Rating: 11.1 kN (2,496 lbf). Static Load Rating: 7.1 kN (1,596 lbf). Limiting Speed: 42,000 rpm on oil/air lubrication, 26,000 rpm on grease. Axial Preload: 100 N as a light-preload pair. Axial Stiffness: 70 N/µm as a light-preload pair. Effective Load Centre: 14.4 mm. Item Weight: 0.17 lb (0.079 kg per bearing). Lubricant: grease or oil. Maximum Operating Temperature: 120 °C. Minimum Operating Temperature: -30 °C. A 25° contact angle takes more thrust than a 15° bearing of the same size and runs at a lower speed ceiling, which makes it the choice where axial load dominates. The laminated phenolic cage is outer-ring guided, light and quiet, and it is what sets the 120 °C ceiling.

Quantity and configuration

Unit Quantity: 2 Pcs. Both bearings are universally ground, so the pair mounts back-to-back, face-to-face or in tandem and reaches the rated light preload when clamped, with no ground spacer.

Fitting notes

Bore Type: Straight, for an interference fit on the shaft with the inner ring rotating. Shaft Abutment Diameter: 30 mm maximum. Housing Abutment Diameters: 42 mm minimum and 44.5 mm maximum. Bearing Fillet Radius: 0.6 mm minimum on the bore side, 0.3 mm minimum on the outside diameter. Pitch circle diameter for oil/air lubrication jets: 32.9 mm. Internal Volume: 3.8 cm³ per bearing, which sets the grease charge. Harmonization Code: 8482.10.50.28.
