NTN 6940-M-C3 single-row deep groove ball bearing. Series 69, the thin-section family. Bore: 200 mm. Outside diameter: 280 mm. Width: 38 mm. Rolling elements: balls, one row, radial contact. Open on both faces.
69 series: thin section, a 40 mm cross-section on a 280 mm outside diameter, so the bearing fits where a medium-section 62 or 63 would not. M: machined brass cage, in place of the pressed steel cage used on the standard 6940. C3: radial internal clearance greater than normal. Equivalent ISO designation: 61940. Punctuation and OEM variants in circulation: 6940 M C3, 6940MC3, 6940C3, 61940 M C3, Komatsu 142-27-11570.
Basic dynamic load rating: 157 kN (35 296 lbf). Basic static load rating: 168 kN (37 767 lbf). Limiting speed: 2 600 rpm on oil, 2 200 rpm on grease. C3 clearance leaves running clearance where the inner ring runs hotter than the outer, or where an interference fit on both rings would otherwise preload the bearing. A machined brass cage tolerates higher temperature, shock loading and marginal lubrication better than a pressed steel cage.
One bearing, complete: inner ring, outer ring, one ball row and the machined brass cage.
Straight bore, 200 mm. Operating temperature range: -40 °C to 120 °C. Supplied with a rust-preventive preservative, no packed grease. Weight: 15.65 lb (7.1 kg). Cross-section: (280 – 200) / 2 = 40 mm against a 38 mm width, the near-square section that identifies the thin-section series.
Construction and earthmoving final drives and swing gearboxes, gear reducers, electric motors, machine tool tables and any location where housing bore is fixed and radial space is short. Komatsu part number 142-27-11570.
Same-designation equivalents: SKF 6940-M-C3, FAG 6940-M-C3, and the ISO 61940 M C3 form. Related sizes: 6940 (pressed steel cage, normal clearance) and 61940 M (normal clearance, machined brass cage).
