Open wire sheaves


100 and 140 mm upright sheaves
The Jefa upright sheaves contain a housing made of machined aluminium extrusion profile. This housing is much stronger and reliable than casted aluminium housings. The housing can contain a black delrin sheave or an aluminium sheave both with a sealed ball bearing. (For outside use a special version with a stainless ball bearing is available at no surcharge, please note on order). The mounting of the sheave assembly is achieved by 4 off widely spread M8 bolts. The sheave can be rotated up to 13 each side to achieve the correct line up with the steering wire.
The 100 mm diameter sheave sets should be used with 5 mm steering wire. The 140 mm diameter sheaves should be used with 6 mm steering cable. It's not advisable to use 6 mm cable on the 100 sheaves as the cable will fatigue quickly due to the too small bending radius.

All Jefa open wire sheaves are CE approved. This means that the sheave set will be able to take more loading than the maximum breaking strength of the appropriate steering wire.

100 and 140 mm articulated sheaves
The Jefa articulated sheaves contain a housing made of aluminium extrusion profile. This housing is much stronger and reliable than casted aluminium housings. The housing can contain a black delrin sheave or an aluminium sheave both with a sealed ball bearing. (For outside use a special version with a stainless ball bearing is available at no surcharge, please note on order). The mounting of the sheave assembly is achieved by 4 off widely spread M8 bolts. The sheave can be tilted and rotated up to 13 each side in the mounting bolts to achieve the correct line up with the steering wire.
The 100 mm diameter sheave sets should be used with 5 mm steering wire. The 140 mm diameter sheaves should be used with 6 mm steering cable. It's not advisable to use 6 mm cable on the 100 sheaves as the cable will fatigue quickly due to the too small bending radius.

100 and 140 mm flat sheaves
The Jefa flat sheaves contain a housing made of aluminium extrusion profile. This housing is much stronger and reliable than casted aluminium housings. The housing can contain a black delrin sheave and an aluminium sheave with a sealed ball bearing. (For outside use a special version with a stainless ball bearing is available at no surcharge, please note on order). The mounting of the sheave assembly is achieved by 4 off widely spread M10 bolts.
The 100 mm diameter sheave sets should be used with 5 mm steering wire. The 140 mm diameter sheaves should be used with 6 mm steering cable. It's not advisable to use 6 mm cable on the 100 sheaves as the cable will fatigue quickly due to the too small bending radius.

100 and 140 mm bulkhead sheaves
The Jefa bulkhead sheaves are designed to be mounted on a bulkhead. The sheave can be rotated in 2 planes over 24 degrees and can be adapted for bulkheads from 10 mm to 30 mm. The Jefa bulkhead sheaves contain multiple parts made of aluminium extrusion profile. These housings are much stronger and reliable than casted aluminium housings. The sheave housing can contain a black delrin sheave or an aluminium sheave with a sealed ball bearing. (For outside use a special version with a stainless ball bearing is available at no surcharge, please note on order). The mounting of the sheave assembly is achieved by 4 off widely spread M8 bolts.

100 and 140 mm self-aligning bulkhead sheaves
The Jefa self-aligning bulkhead sheaves are designed to be mounted on a bulkhead. The sheave can be rotated to align to the cable and can be adapted for bulkheads from 21 mm to 29 mm. The Jefa bulkhead sheaves contain multiple parts made of aluminium extrusion profile. These housings are much stronger and reliable than casted aluminium housings. The sheave housing can contain a black delrin sheave or an aluminium sheave with a sealed ball bearing. (For outside use a special version with a stainless ball bearing is available at no surcharge, please note on order). The mounting of the sheave assembly is achieved by 4 off widely spread M8 bolts.
