Classification of stud type track needle roller bearing :

1) Basic type NUKR series stud type track needle roller bearing
The bolt-axis curve roller NUKR series is a full-load double-row cylindrical roller structure.

2) Eccentric sleeve NUKRE series stud type track needle roller bearing
The bolt-axis curve roller NUKRE series and the NUKR series are similarly full-filled double-row cylindrical roller structures. The only difference is that the NUKRE series has an eccentric sleeve on the bolt shaft.

3) Double raceway PWKR series stud type track needle roller bearing
The bolt-shaft curve roller PWKR series is similar to the NUKR series. It is a full-load double-row cylindrical roller structure. The only difference is that the outer ring of the PWKR is a double raceway, and the two rows of rollers are separated.

4) NUKRA series with side roller stud type track needle roller bearing
The NUKRA series is similar in appearance to the NUKR series. The difference is that NUKRA is a stud bolt, and a roller on one side is added to the end of the bolt shaft, which causes a change in structure. NUKRA is a single-row full complement cylindrical roller structure. This structure is the first of its kind and is patent pending.

5) KR series stud type track needle roller bearing
KR series curved roller bearing is the needle roller cage assembly bearing. The outer ring is axially guided via the rib on the bolt and the retaining ring fixed on the bolt, which can withstand heavy load and medium speed. Since the bearing has more grease storage space, the lubrication cycle is extended.
KR is similar to NUKR except that the KR has a retaining ring at both ends, while the NUKR has a retaining ring at one end.

6) KRV series stud type track needle roller bearing
The KRV series curved roller bearing is a full complement needle roller bearing. The outer ring is axially guided via the rib on the bolt and the retaining ring fixed on the bolt. It can withstand heavy load but low speed, but must be regularly lubricated. fat.
KRV is similar to NUKR except that the KRV has a retaining ring at both ends, while the NUKR has a retaining ring at one end
