Fafnir RCJ1 NT, a four-bolt flange mounted ball bearing unit from Timken’s Fafnir SURVIVOR NT range. Bore / Shaft Size: 1 in (25.4 mm). Housing Style: four-bolt square flange. Material: cast iron, nickel plated. Locking Method: eccentric locking collar. Closure Type: shroud seal. Insert Bearing: G1100KRRB TDCF. Series: Industrial.

RCJ — Fafnir four-bolt square flange housing carrying an eccentric locking collar insert bearing.
1 — shaft size, 1 in.
NT — SURVIVOR NT execution. Nickel-plated housing and corrosion-resistant hardware for washdown, wet and chemically aggressive duty.
G1100KRRB TDCF — the wide inner ring insert bearing fitted in the housing, with its spherical outside diameter seated in the machined housing bore for self-alignment.
Dynamic Load Rating: 15,500 N (3,490 lbf). Static Load Rating: 7,800 N (1,750 lbf).
The nickel plating is the reason to specify the NT over a plain cast iron flange unit. It keeps the housing surface intact under caustic washdown and salt carryover, where a painted cast iron block chalks and rusts at the bolt faces. The eccentric collar grips the shaft by rotating against the extended inner ring in the direction of rotation, so no shaft flat and no machining is needed. The spherical seat between insert and housing lets the bearing take up shaft-to-housing misalignment as the frame is bolted down.
Unit Quantity: 1 Pc. One complete flange unit, nickel-plated housing, insert bearing, eccentric collar and seals assembled.
Bolt Hole Spacing: 69.8 mm (2.748 in). Bolt Hole Size N: 10 mm (0.394 in). Bolt Size: M10. Total Length L: 95.2 mm (3.748 in). Housing Width A: 27.9 mm (1.098 in). Flange Thickness A1: 12.7 mm (0.500 in). Centre of Bearing from Housing End A2: 19.6 mm (0.772 in). Dimension B1: 44.4 mm (1.748 in). Dimension S1: 26.9 mm (1.059 in). Dimension E: 46.6 mm (1.835 in). Dimension d1: 38.1 mm (1.500 in).
Searchable variants of the number: RCJ1NT, RCJ-1-NT, RCJ1 NT, RCJ 1 NT. Timken’s SAP material ID for this item is 100107804. The insert on its own is catalogued as the Fafnir G1100KRRB TDCF.
The plain RCJ1 is the same flange unit and the same 1 in bore without the nickel-plated SURVIVOR NT treatment.
