Fafnir M314KCRDB matched pair of precision deep groove ball bearings, 300 heavy series. Brand: Fafnir (Timken). Part Number: M314KCRDB. Bore: 70 mm. Outside Diameter: 150 mm. Overall Width: 35 mm per bearing. Design Units: Metric. Number Of Rows: 1 per bearing. Rolling Elements: Ball. Bore Type: Straight. Closure Type: Open. Bearing Material: Chrome bearing steel.
Precision Class: P5. Precision Rating: ABEC 5. Cage Material: Phenolic. Cage Type: Machined, outer-ring land-riding. Mounting Arrangement: Back-to-Back. Arrangement / Configuration: Matched back-to-back pair (DB). Series: M300, Fafnir’s heavy dimension series — an M314 carries the ISO 6314 envelope. The CR suffix marks the machined phenolic cage; the DB suffix marks the back-to-back matched pair.
Dynamic Load Rating: 111 kN per bearing. Static Load Rating: 68 kN per bearing. A back-to-back arrangement sets the two contact lines diverging outward, which gives the pair a wide effective support span and high resistance to tilting moments on the shaft. ABEC 5 tightens bore, outside diameter and running accuracy against a standard-tolerance bearing, so the shaft runs truer and the assembly generates less vibration. The machined phenolic cage rides on the outer ring land, staying centred at speed and holding lubricant against the ball pockets. Lubricant: oil or grease. Max Temp: 120°C. Min Temp: -30°C. Internal Clearance: N/A — the pair is set by preload rather than by clearance.
Unit Quantity: 2 Pcs. The two bearings are a matched back-to-back set and mount as a unit. Total Width: 70 mm for the pair as mounted, 35 mm for each bearing individually.
Cross-References: SKF 6314/P5, FAG 6314-TB-P5, NSK 6314 P5 DB, 6314-P5 DB. Each shares the 70 x 150 x 35 mm envelope and the ABEC 5 tolerance class. Harmonization Code: 8482.10.50.68.
MPN Variants: M314KCRDB, M-314-K-CR-DB, M 314 K CR DB, M314K-CR-DB, 6314 T P5 DB, 6314-P5.
