A matched duplex pair of RHP 7005CTDULP4 super-precision angular contact ball bearings. Each bearing has a 25 mm bore, 47 mm outside diameter and 12 mm width, is open on both faces and runs a straight bore. The pair is universally ground with light preload built in.
7005 identifies an angular contact ball bearing in the ISO 70 light series with a 25 mm bore. C sets a 15° contact angle in the RHP scheme. T denotes a phenolic cage. DU marks the bearings as a universally ground duplex set and the following L sets light preload. P4 is the precision class, equivalent to ABEC 7. The carton also carries B7005X2TADULEP7, which reads consistently in the RHP B-series scheme: X2 confirms the 15° angle and EP7 the equivalent precision grade.
A 15° contact angle favours speed and radial stiffness over thrust capacity, which is why this configuration is standard in high-speed spindles. Light preload holds the set rigid at minimum friction and heat rise, giving the highest speed capability of the preload range. The phenolic cage is light and self-lubricating and tolerates high cage speeds. P4 accuracy controls bore, outside diameter and running runout to super-precision tolerances.
Dynamic and static load ratings, limiting speed and temperature limits are published in the specification table on this page.
Two bearings, supplied as a matched universal duplex set. Each is single row and open, with no snap ring, seals or shields.
Universal grinding allows assembly back-to-back, face-to-face or in tandem. A back-to-back or face-to-face arrangement locates the shaft axially in both directions and develops the built-in light preload as the rings are clamped; tandem mounting shares thrust in one direction only. A single row alone takes thrust in one direction. The set is matched and stays together as supplied.
A substitute needs the same 15° angle, the same light preload and the same P4 or EP7 class. The carton cross designation is Fafnir 2MM9105WI DUL. A 7005 with a 25° angle, a different preload letter or a lower precision class shares the 25 x 47 x 12 mm envelope but does not run the same.
