RHP7007TSULP2Super Precision Angular Contact Ball Bearing 35x62x14mm ABEC 9 P2 Phenolic Cage Light Preload Single Universally Ground

Product Description

What this part is

A single RHP 7007 super-precision angular contact ball bearing, 35 mm bore x 62 mm OD x 14 mm wide, with a phenolic cage and universally ground rings set for light preload. The P2 tolerance class puts it at the top of the accuracy range — this is grinding-spindle and precision-machine-tool hardware, not a general-purpose bearing.

Decoding the designation

7007 — ISO angular contact envelope, light series, 35 x 62 x 14 mmT — phenolic cageSUL — single, universally ground, light preloadP2 — ISO tolerance class 2, equivalent to ABEC 9; the RHP alternative marking EP9 on the same bearing agrees with this
This designation carries no contact-angle letter (RHP uses C for 15° and E for 25°), so no contact angle is stated for it here.

What these specs mean in practice

P2 / ABEC 9 is the tightest practical accuracy class: bore, OD, width and running accuracy are all held to a few microns, which is what allows a spindle to hold form and finish at speed. That accuracy only reaches the workpiece if the shaft and housing seats are ground to a comparable class — fitted into an ordinary bore, a P2 bearing performs like a P0 one. Light preload keeps friction and heat low, favouring speed and long grease life over maximum rigidity, and the phenolic cage suits high speed but must be kept away from solvents and steam.

Quantity and configuration

One bearing. Universally ground rings mean this one can be run alone, or stacked with identical bearings back-to-back, face-to-face or in tandem, and the ground offsets will produce the intended light preload without a ground spacer.

Fitting notes

Handle by the rings and mount clean — a P2 bearing shows every particle of contamination. Use the machine builder’s specified shaft and housing tolerances; too tight a bore fit will raise the preload and the running temperature. Where several are stacked, orient per the spindle design and mark faces before removal. Lubricate sparingly with a spindle grease or oil-air feed suited to the speed.

Interchange guidance

Equivalents are 7007-envelope P2 / ABEC 9 light-preload universally ground singles, including the RHP 7007-T-SUL-P2 and 7007TULEP9 forms of this same bearing. Related but NOT interchangeable: P4 / ABEC 7 versions of the same number are a looser class, and SUM / SUH carry medium or heavy preload. A specific contact angle variant (7007C or 7007E) is also a different part from an unlettered one.
