BK1614RS Closed End Sealed Drawn Cup Needle Roller Bearing — 16 × 22 × 14 mm

BK1614RS is a drawn cup needle roller bearing with a closed end and a lip seal on the open side: 16 mm bore (F_w), 22 mm outside diameter, 14 mm outer ring width, closed end depth C₁ 11.3 mm, mass 15 g. It carries 7.37 kN dynamic and 9.8 kN static load and runs to 9 000 r/min. Two things are closed here — the cup bottom stops the shaft and caps the far end, the seal shuts the shaft entry — so a shaft end sitting in a dusty housing needs no end plug and no separate rotary seal. GCr15 rollers, P0/P6, from 100 pieces.

C₁ is the number to check first. The shaft may enter 11.3 mm and no further — the cup bottom is 2.7 mm thick. If your shaft overhangs more than C₁, the bearing will stand off the housing and the seal will not seat.

Why Closed End Plus Seal

Requirement	What BK1614RS does
Shaft must not protrude out of the housing	Closed cup bottom caps the end — no plug, no cap
Dust and chips at the shaft entry	Lip seal on the open side
Grease retention	Closed end plus seal, filled for life
Housing depth	Needs C, not C plus a separate cover
Axial location in one direction	The cup bottom gives a positive stop

The combination is common on gearbox end positions, pump shafts, wiper and actuator motors, and hand-tool gearboxes — anywhere a shaft terminates inside a housing that sees dirt.

Eight Versions of the 16 mm Bore

Designation	Type	D × C (mm)	C₁ (mm)	C_r (kN)	Limiting speed	Mass (kg)	Choose it when
HK1612	open	22 × 12	—	7.37	16 000	0.012	Full speed, full capacity, shaft passes through
BK1612	closed one end	22 × 12	9.3	7.37	16 000	0.014	Shaft ends inside the housing, no seal needed
HK1614 RS	open, sealed one side	22 × 14	—	7.37	9 000	0.013	Dust on one face only
BK1614 RS	closed + sealed	22 × 14	11.3	7.37	9 000	0.015	Shaft end in a dirty environment
HK1616	open, wide	22 × 16	—	10.5	16 000	0.016	More load, no sealing needed
HK1616.2RS	sealed both sides	22 × 16	—	7.37	9 000	0.014	Sealed, shaft passes through
BK1616	closed, wide	22 × 16	13.3	10.5	16 000	0.018	Closed end and maximum load
HK1622	double row	22 × 22	—	12.8	16 000	0.024	Highest load in a 22 mm OD

The closed bottom is free. BK1612 and HK1612 both carry 7.37 kN at 12 mm width — closing the cup costs no capacity.
The seal is what costs. Capacity is unchanged at this width, but limiting speed drops from 16 000 to 9 000 r/min. The seal limits speed, not load.
Width buys load. HK1616 at 16 mm width carries 10.5 kN, 42% more than the 12 mm HK1612. If you need load rather than closure, go wider before going bigger.

The catalogue carries both an open (HK) and a closed (BK) version at nearly every size, with sealed variants on top. When you specify, decide in this order: shaft end inside or through → sealed or open → width for the load.

Typical Applications

Application	Why this combination
Gearbox end positions	Shaft terminates inside the housing, oil and dirt present
Pump and compressor shafts	Closed end caps the bore, seal protects the rollers
Wiper, actuator and small motors	Compact, life-lubricated, no external cap
Hand-tool gearboxes	Dust at the output shaft, short shaft end
Conveyor and door drives	Low-maintenance end support

Shaft, Housing and Installation

Shaft end must stop inside C₁ = 11.3 mm. Check the overhang before you commit the housing depth.
Shaft: 58–62 HRC, h5/h6, ground; raceway Ra ≤ 0.2 µm, seal lip 0.2–0.4 µm.
Housing: N7 press fit, chamfer 0.5 × 20°; bore depth = C plus 0.5 mm clearance.
Press on the closed end face or the outer cup — never through the bore, never on the seal lip.
Orientation matters: the seal faces the dirty side, the closed end faces outboard. Fitting it the other way leaves the seal inside the housing doing nothing.
Grease: leave headspace in a closed cup; a fully packed cavity can push the seal out as it warms.
Do not solvent-wash a sealed unit — the factory fill cannot be replaced.

Frequently Asked Questions

What are the dimensions of BK1614RS?

16 mm bore (F_w), 22 mm outside diameter, 14 mm width, closed end depth C₁ 11.3 mm, 15 g.

What is the difference between BK1614RS and HK1614 RS?

The BK version is closed at one end and HK is open both ends. Both are sealed on the open side and both carry 7.37 kN at 9 000 r/min — the difference is whether the shaft may pass through.

How deep can the shaft enter?

11.3 mm (C₁). The cup bottom is 2.7 mm thick, so the shaft must stop before it.

Does the closed end or the seal limit the speed?

The seal. The open HK1612 runs to 16 000 r/min; the sealed BK1614RS to 9 000 r/min at the same load.

Which way round does it fit?

Seal toward the dirty side, closed end outboard.

Which designations are the same part?

BK1614RS, BK1614 RS and BK 1614 RS; it also interchanges with the same code from INA/FAG, SKF, NTN, NSK and Koyo.

Shaft end, or through shaft?

Send the shaft overhang and the housing depth — we will tell you whether BK1614RS fits as drawn or whether the open HK1614 RS is the right part. Price and lead time within 24 hours on working days.
