A matched duplex set of two single-row super-precision angular contact ball bearings, 35 mm bore, 62 mm outside diameter, 14 mm width each, 28 mm total stack width. The two rings are ground as a pair to a specified heavy preload and mount together as one unit.
7007 — ISO 70-series angular contact ball bearing, bore code 07 = 35 mm boreC — 15° contact angle in the RHP / Timken schemeT — phenolic (laminated fabric) cageDU — duplex, a matched pair ground for mounting togetherH — heavy preload classP4 — ISO P4 precision, equivalent to ABEC 7
A 15° contact angle favours speed and radial stiffness over thrust capacity: it runs faster and carries less axial load than a 25° or 40° bearing of the same envelope. Heavy preload raises axial and radial stiffness and reduces deflection under cutting or reversing load, at the cost of higher running friction and heat generation, so the mount benefits from steady lubrication and controlled housing temperature.
The phenolic cage is light, self-lubricating and quiet at high speed, which is why it is standard on grease- and oil-lubricated machine tool spindle bearings. P4 accuracy holds tight bore, outside diameter and runout tolerances suited to spindle work.
Matched duplex pair, 2 Pcs, supplied as one preload-matched set. The set is a single unit for fitting purposes.
Duplex sets carry etched or marked V-lines across the outer ring faces that define the arrangement; assembling with the marks aligned reproduces the ground preload. The pair goes onto the shaft as a stack, clamped between a square shaft shoulder and a lock nut, with the housing bore and shaft seat within the accuracy the bearing class assumes.
Genuine interchanges are 15° duplex heavy-preload P4 sets in the same envelope: NSK 7007CTRDUHP4, Fafnir / Timken 2MM9107WI CR DUH, and the RHP 7007X2TADUHEP7 designation. A 7007 in E / A5 / 25° form, or the same envelope at light or medium preload, is a related size rather than an interchange, because contact angle and preload class both change spindle stiffness and speed.
