MRC 7107KRDS angular contact ball bearing, supplied as a matched duplex set of two. Bore 35 mm, outside diameter 62 mm, width 14 mm per bearing. Straight bore, open, chrome steel rings and balls. The envelope corresponds to an ISO 7007.
In the MRC scheme the leading 7 places the bearing in the 25° contact angle family, so a 7100KR reads 25° where a bare 100KR reads 15°. Bore code 07 gives the 35 mm bore, and the KR series carries the ISO 70 light dimension envelope. D marks a matched duplex pairing. The carton marking BKE#5 corresponds to ABEC 5 precision.
A 25° contact angle carries more thrust and runs at lower speed than a 15° bearing in the same envelope, which suits a spindle or gearbox position that sees real axial load rather than one chasing maximum rpm. ABEC 5 holds bore, outside diameter and running accuracy tighter than a standard bearing, which keeps shaft runout predictable. A matched duplex pair is ground as a unit so the two bearings share load evenly and hold preload without shimming.
Two bearings, factory matched as a duplex pair and kept together as a unit. Because the pair is preloaded by grinding, it carries no radial internal clearance value.
Straight bore on an interference fit shaft seat, outer rings located in a bored housing. The ground offset sets the preload once the pair is clamped, so no shim stack is required. Both rings of a matched pair are installed in the orientation marked on their faces.
Same-envelope equivalents at 25° in ISO terms are a 7007 AC pairing: SKF 7007 ACD/P5 DGA, FAG 7007-B-TVP-UA and NSK 7007A5. A 107KRDS without the leading 7 shares the 35 x 62 x 14 mm envelope at a 15° contact angle, making it a related size rather than an interchange.
