SUC207 is a standard metric model in the "Stainless Steel Outer Spherical Ball Bearing" series (with variants such as SUC207-20, -21, -22 corresponding to imperial shaft diameters). Its core task is to directly replace ordinary bearing steel UC207 in humid, salt spray, chemical cleaning, or food grade flushing environments, achieving corrosion-resistant, washable, and maintenance free seat installation.

1、 Key dimensions and loads
Inner diameter d: 35 mm
Outer diameter D: 72 mm
Total width B: 42.9mm
Basic rated dynamic load Cr: 20.1 kN; Static load Cor: 15.6 kN
Extreme speed (grease lubrication): 3700 r/min
Working temperature: -20 ℃~+120 ℃ (standard silicone seal)
Locking: 2 M8 × 1 set screws; No keyway or disassembly sleeve is required during installation
2、 Materials and Sealing
Ring/rolling element: AISI 440C (9Cr18Mo) stainless steel, vacuum quenched and tempered HRC ≥ 58
Holder/dust cover frame: AISI 304
Sealing: double-sided contact silicone sealing ring, waterproof, alkali resistant, and salt spray resistant; Optional food grade solid grease (suffix FG1) achieves lifelong lubrication free
3、 Typical usage scenarios
Food and Beverage
Fruit and vegetable conveyor, filling machine, CIP cleaning pump, homogenizer; The whole machine can be washed under high pressure without rust powder falling off.
Medicine, Biochemistry
Centrifuge, reactor stirring, purified water circulation pump; Meet the requirements of "easy to clean and corrosion-resistant" in GMP workshops.
Chemical and marine industries
Seawater desalination pump, electroplating line hoist, outdoor belt conveyor roller; Resistant to salt spray and weak acids and bases.
Low temperature/high humidity equipment
Ice maker, cold storage conveyor, tunnel freezer; 440C maintains toughness at low temperatures and will not crack brittle.
General Conveyor and Agricultural Machinery
Packaging machine, labeling machine, organic fertilizer pellet machine, cleaning vehicle brush roller; In situations where external spherical alignment is required and there is no fear of washing.
4、 Supporting seat body (complete set of stainless steel)
SUCP207 (vertical seat)
SUCF207 (square flange with four holes)
SUCFL207 (diamond flange)
SUCT207 (slider seat)
SUCPA207 (suspended)
There is no risk of coating peeling off on the entire machine, and it is used to flush the environment in one step.
one-sentence summary
SUC207 is the UC207 that is "not afraid of water flushing, not afraid of salt spray, and does not need to be refilled with oil". Wherever UC207 is used, it is afraid of rust, needs to be adjusted, and needs to be washed frequently, so it is directly replaced -35mm axis food filling machines, seawater pumps, and pharmaceutical centrifuges are the most common positions
