Seventeen models of traverse units are available with axial thrust ranging from 5 Kg to 280 Kg and suitable for shaft dia 10 mm to 80 mm. Traverse units are available in two designs.
Type 1: With Three Rolling Rings
Type 2: With Four Rolling Rings
Type 1: Traverse Unit With Three Rolling Rings:
1) HT 1 (Shaft Ø15mm)
2) HT 2 (Shaft Ø 15mm)
3) HT 3 (Shaft Ø 20mm)
4) HT 22 (Shaft Ø 22mm)
5) HT 3N (Shaft Ø 30mm)
6) HT 4 (Shaft Ø 40mm)
7) HT 5 (Shaft Ø 50mm)
8) HT 6 (Shaft Ø 60mm)
9) HT 8 (Shaft Ø 80mm)
Type 2: Traverse Unit with four Rolling Rings:
1) 4RR 15 (Shaft dia 15mm)
2) 4RR 20 (Shaft dia 20mm)
3) 4RR 22 (Shaft dia 22mm)
4) 4RR 30 (Shaft dia 30mm)
5) 4RR 40 (Shaft dia 40mm)
6) 4RR 50 (Shaft dia 50mm)
7) 4RR 60 (Shaft dia 60mm)
8) 4RR 80 (Shaft dia 80mm)
Traverse Units with four Rolling Rings are heavy-duty models. The extra Rolling Ring increases the axial thrust capacity by 100 %.
There are no significant changes in outside dimensions of models of 40 mm diameter shaft and above. The dimensional change mainly in length for models suitable for 30 mm diameter shaft and below (4RR 15, 4RR 20, 4RR 22, 4RR 30.) is minimum.
Traverse Units with four Rolling Rings enables the use of a smaller diameter shaft for application in high thrust requirements, cost savings and also where only limited space is available. |
