BS60 Bulkhead steerer |
The Jefa BS60 type bulkhead steerer incorporates
twin high efficiency 25 mm ball bearings, which are double sealed and
pre-lubricated for a long and maintenance free life. The lip seal at the
front is the especially developed Jefa PUR seal, which contains no metal
parts for a life long problem free usage. The stainless steel steering shaft has a diameter of
25 mm to guarantee
a stiff and strong steering arrangement for wheels up until 1300 mm
diameter. Above 1300 mm wheel size one should add a support bearing at
the aft side of the steering shaft (like the BS30 unit). The maximum
wheel size accepted is 1500 mm, above 1500 mm wheel diameter the BS30
should be used. The large internal brake disk provides an efficient and strong braking
arrangement. The number of turns achieved with the various sprockets can
be found in our sprocket table. Brake spinner is not included and should be ordered separately. |
