Product Description

What this part is

A single-row deep groove ball bearing, 90 mm bore by 140 mm outside diameter by 24 mm wide, with a pressed steel shield on one side and the other side left open. Deep groove ball bearings carry radial load plus axial load in either direction. The one-shield form lets lubricant reach the bearing from the open face while the shield closes off the side facing the dirty end of the machine.

Designation breakdown

6: single-row deep groove ball bearing.

0: dimension series 60, the light section for this bore.

18: bore code, 18 x 5 = 90 mm bore.

Z: a single pressed steel shield, on one side only. Two shields are 2Z; contact rubber seals both sides are 2RS1.

No clearance suffix: normal (CN) radial internal clearance.

What these specs mean in practice

The single shield is the whole point of this part number. A 6018-Z is not interchangeable with a 6018-2Z: the open face means the bearing depends on the housing to hold grease or supply oil on that side, and it does not retain a factory grease fill on its own the way a double-shielded bearing does. A 6018-2Z in its place closes the bearing off from the gearbox oil that was feeding it, and a 6018-Z in a double-shielded position admits whatever the housing lets in.

A shield is not a seal: it runs with a small gap at the inner ring, costs almost no friction and does not limit speed, and it holds back dry dust and coarse debris rather than water or coolant.

Clearance is normal (CN), which suits a shaft and housing at similar temperatures with a standard interference fit. A 6018/C3 is the greater-clearance variant.

Interchange guidance

Genuine interchanges are same-envelope single-shielded bearings: FAG 6018-Z, NSK 6018Z, NTN 6018Z and Koyo 6018Z. A 6018-2Z (two shields), a 6018-2RS1 (contact seals both sides), a plain open 6018 and a 6018/C3 (greater clearance) are related parts that change lubrication, sealing or fit-up.
