Pre-installation inspection
Visually check raceways and rollers under good light for nicks, corrosion, stains, brinelling, or burrs.
Pass a clean cotton swab lightly over surfaces—snagging indicates a defect.
Verify bore and shaft/housing fits meet design tolerances (measure with calibrated micrometers / bore gauges).
Shaft & housing preparation
Ensure seating surfaces are round, clean, and free of raised metal (no more than 50% of tolerance consumed by form error).
Surface finish guideline: Ra 0.2–0.8 μm (8–32 μin) typical for seats.
Deburr keyways and threads; cover keyways during mounting to protect rollers.
Mounting (general)
Do not separate H715345/H715311 bearing rollers from cone.
Apply a thin film of clean base oil (not heavy grease) on seating surfaces to ease mounting and prevent fretting.
Press or heat-mount the cone (if interference fit) using an induction heater with temperature control; do not exceed 120 °C (250 °F) unless manufacturer allows higher. Never flame-heat.
Press only on the ring being mounted (avoid transmitting force through rollers).
After cup installation, verify it seats square against shoulder; use feeler gauge—no light leakage.
Replacement guidelines
Replace as a set (cone and cup together) to maintain original geometry.
Do not mix components from different manufacturers or sets unless specified interchangeable.
Always inspect mating parts (shaft/housing) for wear or fretting before reusing.
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.
