RHP7006TUEP3Angular Contact Ball Bearing – Straight Bore, 30 mm ID, 55 mm OD, 13 mm Width, Open, Laminated Phenolic Cage

Product Description

What this part is

RHP 7006TUEP3 super-precision single-row angular contact ball bearing. Brand: RHP, part of the NSK Group. Manufacturer Part Number: 7006TUEP3. Bearing Type: Angular Contact Ball Bearing. Number Of Rows: 1. Rolling Elements: Ball. Bore: 30 mm. Outside Diameter: 55 mm. Width: 13 mm. Bore Type: Straight. Closure Type: Open. Series: 70, ISO dimension series 10. Bore Code: 06. Country of Origin: United Kingdom. Bearing Material: carbon chrome bearing steel to BS970 534A99 / 535A99, equivalent to SAE 52100, through hardened and heat treated for dimensional stability.

Decoding the designation

Precision Class: P6, written EP3 in the British Standard BS292 scheme and equal to ABEC 3. Cage Material: laminated phenolic resin. Cage Type: machined, outer-ring guided. Face Control: universal. Universal face control means the inner and outer rings are ground to the same width and the relative positions of the faces are adjusted at manufacture, so the bearing mounts back-to-back or face-to-face without altering the set value and shares load equally when mounted in tandem.

What these specs mean in practice

Maximum Operating Temperature: 120 °C, set by the laminated phenolic cage. Mass: 0.114 kg per bearing. Internal Free Volume: 5.3 cm³. An outer-ring guided laminated phenolic cage is light and self-lubricating, so it runs quieter and generates less heat at spindle speeds than a steel or brass cage, and the low cage mass keeps centrifugal loading on the pockets down. The internal free volume is the figure grease quantity is calculated from.
