INA ZKLF Series Angular Contact Bearings: Bearings of series ZKLF are double row axial angular contact ball bearings with an outer ring suitable for flange mounting and integral seals. These bearings are predominantly used for the bearing arrangements of screw drives and are an extremely economical solution for criteria such as a simple adjacent construction and low fitting costs. The larger sizes of these bearings – with a bore diameter of 60 mm to 100 mm are particularly suitable for bearing arrangements of large threaded spindles or rotating threaded nuts, in other words screw drives with a static spindle.
Double row axial angular contact ball bearings of series
ZKLF...2RS have two rows of balls with a contact angle of 60 Degrees.
The bearings are sealed on both sides with rubber seals and are
greased for life for the majority of applications. Additional seals
in the adjacent construction are not required.
In most applications, the initial greasing is sufficient for the
whole operating life. If necessary, re lubrication can be carried
out via a threaded connector from a central lubrication system on
the flange side or by means of a lubrication groove and
lubrication hole via the adjacent construction.
The axial run out tolerance corresponds approximately to P2 in
accordance with DIN 620. Benefits: Cost effective solution, re-lubricatable, bolt in place, low down time

When I saw the code on this I was nearly sick, it looks like an explosion on the countdown set. But you people helped me find it very quickly and dispatched it out to me on the same day, with delivery the day after. Very impressive service all around and I am happy and confident to come to you in the future. Best Regards, Tom.
