Product Description

What this part is

Dodge F4B-GT-110L, a complete cast-iron four-bolt flange bearing unit with a Grip-Tight concentric adapter insert. Dodge Part Number: 129650. Housing Style: F4B, four-bolt flange. Bore / Shaft Size: 1-5/8 in (1.625 in, 41.28 mm), straight bore. Bore Length: 2.01 in (51.05 mm). Rolling Elements: Ball. Number Of Rows: 1. Insert Outer Ring: Spherical, self-aligning. Locking Method: Grip-Tight concentric adapter. Housing Material: Cast iron. Duty Type: Standard duty. Expansion Type: Non-expanding. GTIN: 782475889457. Country of Origin: United States.

What the Grip-Tight locking does

Locking Method: Grip-Tight concentric adapter. A Grip-Tight insert clamps the shaft through a tapered adapter sleeve and collar rather than through setscrews, so the grip is distributed all the way round the shaft instead of concentrated at two points. That gives higher holding torque against axial creep and reversing loads, and it locates the bearing concentric to the shaft rather than pushing it off centre the way a setscrew does. It also leaves no setscrew dimples in the shaft, so the same shaft can be re-used at the same position.

Load and speed data

Dynamic Load Rating: 29.5 kN. Static Load Rating: 19.8 kN. Limiting Speed: 5,500 rpm. Precision Rating: ABEC 1 / P0. Internal Clearance: CN. The spherical outer ring on the insert seats in a matched spherical housing bore, so the unit takes up shaft misalignment and mounting-surface error without loading the raceways edge-on — which is what keeps a standard-duty unit at these ratings on a real fabricated frame rather than a machined one.

Sealing, lubrication and temperature

Seal Type: Contact seal. Lubricant: Grease. Relubrication: Regreasable in service through the housing fitting. Operating Temperature Range: −20 °C to +120 °C. Contact seals rub against the insert outer ring, so they exclude washdown water and airborne dust that a labyrinth or flinger would pass, and they hold grease in the bearing cavity between service intervals.

Housing style and bolt pattern

Housing Style: Four-bolt flange, surface mount. Number Of Bolt Holes For Fasteners: 4. Bolt Center To Center Length: 4.13 in (104.9 mm). Mounting Arrangement: Surface mount — the flange face bolts flat to a machine wall or bulkhead and the shaft passes through it, so the unit carries a shaft perpendicular to the mounting surface rather than parallel to it as a pillow block does.

Interchange guidance

Cross-Reference 1: SKF F4B 1.5/8 TF. Cross-Reference 2: Browning F4B-S-226. Both are four-bolt flange units on the same 1-5/8 in shaft and the same F4B envelope. Searchable variants of this designation: F4B-GT-110L, F4BGT110L, F4B GT 110L, F4B GT 110-L, and the Dodge item number 129650.
