Published ratings and mounting data

Dynamic Load Rating: 25.5 kN (5 730 lbf). Static Load Rating: 15.3 kN (3 440 lbf). Limiting Speed: 4 000 rpm. Precision Rating: ABEC 1 / P0. Item Weight: 1.00 lb each. Lubricant: grease. Relubrication: yes. Operating temperature range: −20 °C to 100 °C.

Decoding the designation

RA: Consolidated insert ball bearing with an extended inner ring and eccentric locking collar. 1: shaft one inch or over. 06: the additional sixteenths, giving 1-3/8 in. Consolidated Bearings is a US importer brand whose RA series follows the common insert-bearing interchange.

Quantity and configuration

Unit Quantity: 4 Pcs. Four inserts, each with its eccentric collar — enough for two two-bearing shafts. These rebuild existing mounted units with a sound housing: pillow blocks, two- or four-bolt flanges and take-up blocks with a spherical insert seat.

What these specs mean in practice

An eccentric collar grips by cam action and leaves the shaft unmarked, so plain cold-drawn shafting is acceptable and the insert can be repositioned. The collar is tightened with the direction of rotation, which makes it a unidirectional-drive fitting; setscrew inserts serve hard-reversing drives.

Rubber contact seals on both sides hold water and fine dust out more effectively than shields, at the cost of a little drag and a lower speed ceiling, which is why the limiting speed sits at 4 000 rpm. That suits washdown-adjacent and dirty conveyor work.

The spherical outer race seats in a crowned housing bore and lets the mounted unit align itself to the shaft.

Interchange guidance

Eccentric-collar inserts at 1-3/8 in bore include Fafnir RA106RR, Timken RA106RR, SKF YET 207-106, Link-Belt UG-222, SealMaster ER-22 and INA GRAE35-NPP-B. Insert outside diameter and overall width govern the housing fit rather than bore alone, so the housing seat decides a cross-brand substitution. A setscrew-locking insert of the same bore is a related build, and RA-103 (1-3/16 in) and RA-107 (1-7/16 in) are the adjacent sizes in the same series. Searchable variants of this number are RA-106, RA106, RA 106 and CONS RA-106.
