MRC 7126KRDT angular contact ball bearing. Envelope: 130 mm bore × 200 mm outside diameter × 33 mm width per bearing. Series: 7100K angular contact extra light. Contact angle: 15°. Closure: open. Rolling elements: balls. Bearing material: bearing steel.
Base number: 7126. Bore code 26 gives a 130 mm bore. Type letter R sets the 15° contact angle and a counterbored outer ring. Execution code DT is a tandem duplex pair. Searchable forms: 7126KRDT, 7126 KR DT, 7126-KR-DT, 7126KRDT ABEC5.
A 15° contact angle carries less thrust and more speed than a 40° angle, and it holds shaft position closely under combined radial and light axial load. The counterbored outer ring gives a single defined thrust direction per bearing. A machined phenolic cage runs light and quiet at speed and tolerates oil-lubricated high-rpm service. Limiting speed on the record: 4300 rpm. Dynamic load rating: 148 kN / 33300 lbf. Static load rating: 156 kN / 35100 lbf.
Two pieces ship, a factory tandem duplex pair. Tandem execution places both contact angles in the same direction, so the two bearings share one axial load path and roughly double the thrust capacity of a single bearing in that direction. Stacked total width for the pair: 66 mm. Carton arrangement code: DT.
Mounting arrangement: universal ground, which allows the pair to be assembled tandem. Bore type: straight. Internal clearance: N/A — a tandem duplex pair is ground for preload, so a running-clearance class has no meaning here. Operating temperature range on the record: −30 °C to 120 °C. Lubrication: oil or grease suited to a phenolic cage.
The MRC 12x-R block steps two designation units per 10 mm of bore, and its envelopes sit outside the ISO 72xx and 74xx dimension series. No ISO cross-reference is published for a 12x-R part. Interchange is by envelope and contact angle: 130 × 200 × 33 mm, 15°, tandem duplex, machined cage.
Country of origin: United States. Condition: new old stock, open box. Harmonization code: 8482.10.50.
