How the 6416-2RS model number is decoded
In the 6400-series (ISO 15 diameter series 4) the last two digits encode the bore: 6416 carries bore code 16 = 80 mm. Outside diameter 200 mm and width 48 mm come from the ISO 15 boundary-dimensions general plan. Suffix -2RS denotes two contact-type elastomer seals over a lifetime grease fill; the sealing lips add drag compared with open or shielded versions. For normal-load mounting with a rotating inner ring on a 80 mm shaft, typical catalogue practice is a k5 shaft seat with an H7 housing bore — verify against the actual load direction and magnitude.
Typical equipment & failure modes
Common applications
- heavy conveyors
- pulp and paper machinery
- medium and heavy industrial drives
- large gearboxes
Known failure patterns
- seal-lip hardening and loss of pre-grease in sustained high-temperature service
- grease-life expiry in the sealed-for-life cavity (no relubrication path)
- brinelling from static overload or hammering during mounting
- false brinelling from vibration while the shaft is stationary
Selection pitfalls — read before you substitute
- Mount this 80 mm bore bearing by heating the inner ring (induction heater, max 120 °C) — never drive it home through the outer ring or balls, that brinells the raceways.
- The 64xx heavy section at 80 mm bore (200 mm OD) is built for high-load, lower-speed duty; specifying it in a high-rpm motor gives excess heat and short grease life — use 62/63 there.
- Contact seals add drag and heat: 6416-2RS runs slower and cooler-limited than the open 6416; rubber lips are generally limited to roughly 80–110 °C continuous depending on grease, and C3 clearance is the common hot-duty choice.
- Never wash a sealed 6416-2RS in solvent or press it home via the outer ring; solvent destroys the grease thickener and mounting force through the seal deforms the lip.
- A 80 mm bore listing showing the right d/D/B but no standard or precision-class reference may be a loose-tolerance import; measure bore/OD spread before fitting it to a machined shaft.
Frequently asked questions
What are the dimensions of a 6416-2RS bearing?
A 6416-2RS deep-groove ball bearing has a 80 mm bore, 200 mm outer diameter and 48 mm width (3.15 × 7.874 × 1.89 in), per ISO 15 boundary dimensions. It is fitted with two contact rubber seals and is normally pre-greased. Geometry-based estimated mass is about 6463 g for a steel-cage unit; catalogue masses vary slightly with seal and cage design.
How does the 6416 bore code work?
The last two digits of 6416 are bore code 16, giving 16 × 5 = 80 mm bore. The 200 mm outside diameter and 48 mm width follow the ISO 15 diameter series, not the bore code alone.
What does the 2RS suffix on 6416-2RS mean?
2RS means two contact elastomer seals, one each side, usually over a lifetime grease fill. Sealing against dust and moisture is better than ZZ shields, but the lip drag lowers the speed and temperature ceiling.
How does the 6400 compare with other series at the same 80 mm bore?
The '4' is the heavy diameter series: 200×48 mm, 60.0 mm radial section at 80 mm bore — the highest-capacity single-row 6xx option here, aimed at lower-speed, high-load shafts.
Are 6416 bearings from different brands interchangeable?
For boundary dimensions, yes: every brand's 6416 uses the same ISO 15 envelope (80×200×48 mm). Load ratings, limiting speeds, clearance, precision class and sealing design can differ, so verify those in the supplier catalogue when substituting. Seal suffixes also differ by brand (2RS, DDU, LLU and similar).
