1. Type & Design: HM516449A-HM516410 is single-row tapered roller bearing with conical raceways and tapered rollers for combined load handling.
2. Load Capability: Bearing HM516449A/10 supports high radial loads and axial load in one direction; axial capacity increases with larger contact angle.
3. Combined Loads: Geometry enables efficient accommodation of simultaneous radial and thrust loads.
4. Separable Components: HM516449A/HM516410 bearing comes as as cone HM516449A (inner ring + rollers + cage) and cup HM516410 (outer ring) for easy mounting, dismounting, inspection, and maintenance.
5. Versatility: SET421 bearings are ideal where adjustable preload, high load capacity, and precise shaft guidance are required—typical uses include truck and trailer drive axles, agricultural equipment, and gearboxes.

Q1: What is the delivery time for an order?
We currently hold 175 pieces of SET421-900SA bearings in stock. Any order up to 175 units ships within 2–3 days after we receive your payment. For quantities above 175, the production lead time is about 20–30 days.
Q2: Is there a warranty on the bearings?
Yes. We provide a 1-year warranty.
Q3: What is the normal shelf life of a bearing?
Bearings manufactured from 52100 chrome steel generally maintain their quality for at least 2 years when stored under proper conditions. If they have been in storage longer than two years, we advise checking for corrosion, unusual noise, or grease degradation before shipment or installation.
Comparison helps when dimensional fit is only part of the decision and load direction, sealing, clearance, speed, temperature, or repeat-order stability still need to be confirmed. Reviewing one or two nearby options early usually reduces sourcing mistakes later.
Buyers normally confirm the part reference, main dimensions, application, speed range, operating environment, sealing needs, and any packaging or marking requirements. That gives the supplier a cleaner basis for confirming availability and suitable alternatives.
A quick review of Taper Roller Bearings, one more commercial destination, and one practical guide usually saves time. That combination helps separate simple replacement orders from jobs that still need fit or application review.
Because it makes later decisions faster. When sizing notes, application cues, and nearby options stay close to the product, engineering, purchasing, and maintenance teams can revisit the same logic without starting the review from zero.

Buyer FAQ
Confirm the bearing number, bore size, outside diameter, width, seal or shield type, cage material, clearance, precision level, quantity, and application. These details help prevent a size match from becoming a performance mismatch.
Yes. Replacement and repeat orders are easier when the original marking, measured dimensions, photos, application, and quantity are available. If the marking is unclear, the team can start from the size and working condition.
This item is handled within the Taper Roller Bearings family. Comparing the family page can help buyers review similar sizes, seal options, load direction, and related bearing choices before requesting a quote.
Price and lead time can change with quantity, stock availability, precision grade, clearance, material, cage, seal or shield type, lubrication, packaging, and whether the order needs standard matching or custom production.
Inspection can include material review, dimensional measurement, noise and vibration checks, surface and crack checks, visual review, and packaging inspection according to the confirmed order requirements.
