TIMKEN 553-SB tapered roller bearing cup

TIMKEN 553-SB belongs to tapered roller bearing cup, part of our Bearings range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for 553-SB and any equivalents.

In a tapered roller bearing, the cup is the outer ring that seats in the housing while the cone carries the rollers and the shaft. Timken's TSF line covers single-row cups of this type, and each one is matched to a cone sharing the same basic number to make a complete assembly. That assembly takes radial and axial load in one direction, which is why these cups show up in gearboxes, wheel hubs and other industrial equipment where precision and load capacity matter. MR Industrial Accessories supplies this cup within its bearing range.

Reading a TSF code is straightforward once you know the pattern. Take 553-SB: 553 is the basic number that ties the cup to its matching assembly, and SB marks the cup variant with its own dimensional characteristics. Cups in the TSF family are single-row and are meant to be mounted with cones from the same series. If the nomenclature is unclear, send us the code and we will walk you through it.

You will find these cups in demanding settings such as metallurgy, cement, mining and food processing, and in speed reducers, conveyors, mills and earthmoving machinery. Because they handle combined loads, they suit shafts that carry heavy mechanical demand. We supply them both for replacement work and for new projects.

Selection starts with the cone you plan to use, since cup and cone must share the series and basic number. Fitting calls for accurate alignment and proper lubrication, and how well the assembly seals depends on the design of the application. Follow the equipment manufacturer's recommended axial clearance to avoid early failures.

Timken cups can be replaced by cups from other makers that work to the same dimensional standards, including equivalent series from SKF, FAG or NSK. Confirm the basic number and tolerances before committing, since compatibility depends on them. Send us the original code and we will point you to the alternative that fits.

For this cup or its matching cone, message us on WhatsApp with 553-SB or the full bearing designation. We reply promptly with a quote and help you confirm the selection.
