Felt slide bearing — a genuine BMW part, number 52 10 8 176 226. The number stamped on the part is 52108176226; BMW's catalog files it under the short number 8176226. You will find it on our Interior Body shelf, under Tail trim.
It fits every E36 body style (318i, 318ti, 320i, 323i and 325i, 1992–1999), with the M40, M42, M43, M44, M50 or M52 engines — and the European-market versions.
BMW draws it on 2 diagrams, among them Front Seat Rail Mechanical/Single Parts (52_0621) and Front Seat Rail (52_0727). BMW's catalog calls for two of these at each place it is fitted. It weighs about 14 g (under 0.1 lb).
We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
