| Body diameter | 127-273 mm (5-10 3/4") |
| Length | 673-781mm (26 1/2-30 3/4") |
RP432 Static deck bushings
Sandvik deck bushings centralize the drill pipe over the hole, prevent misalignment of the bit and drill string and extend the life of the bit and drill string.
Features and values
- Best for operation with DTH (down-the-hole drilling)
- High alloy, heat-treated materials provide longer service life
Key specifications
| Outside body diameter | 191-483 mm (7 1/2-19") |
| Inner sleeve diameter | 107-340 mm (4-13 3/8") |
| Flange diameter | 214-510 mm (8-20") |
RP434 Rotary deck bushings
Sandvik deck bushings centralize the drill pipe over the hole, prevent misalignment of the bit and drill string and extend the life of the bit and drill string.
Features and values
- Three ball bearing race design insures smoother, longer bearing life
- More cost effective than static bushings
Key specifications
| Outside body diameter | 191-483 mm (7 1/2-19") |
| Inner sleeve diameter | 107-340 mm (4-13 3/8") |
| Flange diameter | 214-510 mm (8-20") |
RP452 Rotary adapter sub
Sandvik rotary adapter subs are used to connect the various components throughout the entire drill string from the drill bit to the rotary head. They are available as bit (bottom) subs, top (spindle) subs, cross-over subs, and thread-saver subs.
Features and values
- Hard face material in the 58 to 60 Rockwell C range
- Hard facing available on all subs (optional)
- Optimum hard material wear protection on bit subs
Key specifications
| Outside diameter | 89-311 mm (3 1/2-12 1/4") |
| Standard length | 457-1067 mm (18-42") |
| Specified wrenching | Flats, Squares, Slots |
RP425 Water separating bit sub
The RP425 protects bit bearing life by limiting dust suppression water from entering the bearings, protecting them from water-induced corrosion. It does not require any changes to the drilling parameters, and it eliminates bit sub expenditures.
Features and values
- Highly wear-resistant high alloy steel
- Either standard cross-over sub or 3 or 4 blade reamer with offset blades
