F 210 vs FC 210 vs FL 210 Housings: UC 210 Insert Fitment Guide
The UC 210 flange housing assembly utilizes the 50 mm bore UC 210 insert bearing paired with a specific cast iron housing style to secure rotating shafts. Choosing between the square F 210, round FC 210, or two-bolt FL 210 housing depends entirely on your machinery's mounting frame, bolt-hole arrangement, and physical space limits. Every housing in the 210 series accepts the exact same 50 mm UC 210 insert bearing, but their external geometries are non-interchangeable.
Matching the correct housing code ensures proper bolt alignment, rigidity, and radial support across industrial equipment. In Pakistan, plant managers and procurement engineers rely on exact part series matching to prevent structural alignment failures, equipment downtime, and unnecessary retrofit costs.
What are the dimensions and specs of the UC 210 insert bearing?
The UC 210 insert bearing features a 50 mm bore, 90 mm outside diameter, and an inner ring width of 51.6 mm[1]. It belongs to the UC 200 series of deep groove radial insert bearings, manufactured with a spherical outer ring that sits inside a matching spherical housing seat[1][2]. This spherical design permits initial self-alignment during mounting to absorb minor shaft flex or base misalignment[1]. Shaft locking is achieved through two set screws located on the extended inner ring.
| Parameter | Specification |
|---|---|
| Bearing Designation | UC 210 |
| Bore Size (d) | 50 mm[1] |
| Outside Diameter (D) | 90 mm[1] |
| Inner Ring Width (B) | 51.6 mm[1] |
| Locking Mechanism | Set Screws |
| Outer Ring Profile | Spherical[1] |
| Catalog Variants | UC 210 (Metric 50 mm), UC 210-32 (Imperial 2-inch)[3] |
| Brands Carried | HI-TEC, GMB |
Selecting the right variant matters when ordering replacements. While the standard UC 210 features a 50 mm metric bore[1], imperial applications use the UC 210-32 variant designed for 2-inch shafts[3]. Standardizing on the correct UC 200 series insert guarantees smooth rotational movement across heavy-duty conveyors, packaging machines, and agricultural equipment.

What is the difference between F 210, FC 210, and FL 210 housings?
Housing codes denote distinct mounting shapes: F 210 is a square four-bolt flange, FC 210 is a round spigoted flange, and FL 210 is a two-bolt oval flange. While all three cast iron housing styles seat the identical 50 mm UC 210 insert bearing, they serve different structural mounting patterns on machinery frames.
| Selection Criteria | F 210 Housing | FC 210 Housing | FL 210 Housing |
|---|---|---|---|
| Flange Shape | Square[1] | Round (Cartridge Profile)[4] | Oval / Diamond[1][5] |
| Bolt Configuration | 4-Bolt Square | 4-Bolt Circular | 2-Bolt In-Line |
| Mounting Alignment | Flat machine walls & side panels | Spigoted circular frame cutouts[4] | Narrow frames & space-restricted side walls[5] |
| Primary Strength | Maximum 4-point rigid support[6] | Precision centered mounting[4] | Compact footprint & fast installation |
| Catalog Unit | F 210 housing | FC 210 housing | FL 210 housing |
The square F 210 four-bolt housing distributes load across four mounting corner bolts, offering rigid support for heavy industrial machinery walls[6]. The round FC 210 housing features a machined spigot or cartridge pilot edge on the backside, centering the unit precisely inside circular machine wall cutouts[4]. The oval two-bolt FL 210 housing provides a narrow profile, reducing mounting footprint where frame space is tight[5].
Are F 210, FC 210, and FL 210 bearing housings interchangeable?
Bearings sharing a series number are not interchangeable, as mounting geometry dictates replacement fitment despite accepting the same 50 mm UC 210 insert[1]. A frame drilled for a four-bolt square F 210 unit will not accept a two-bolt oval FL 210 housing or a round FC 210 spigoted unit without extensive mechanical alterations, drilling, or welding.
- Bolt Pattern Differences: F 210 uses a square four-bolt pattern[6], FL 210 uses two bolt holes spaced along a straight axis[5], and FC 210 uses four holes evenly spaced around a circular pitch[4].
- Pilot Edge Fitment: The FC 210 cartridge housing features a spigot shoulder requiring a matching circular frame cutout for flush seating, which flat F 210 or FL 210 bases lack[4].
- Structural Space: Oval FL 210 units fit narrow vertical channels where square F 210 flanges would physically hit surrounding machine guards[5].

Frequently Asked Questions
What housing fits a UC 210 insert bearing?
A UC 210 insert bearing fits any 210 series flange or pillow block housing, including the F 210 square four-bolt flange, FC 210 round spigoted flange, FL 210 oval two-bolt flange, and P 210 pillow block. All 210 series housings feature the matching 90 mm spherical internal seat required for the UC 210 insert.
What is the difference between F 210, FC 210, and FL 210 housings?
The primary difference lies in their external mounting geometry. F 210 is a square flange with four mounting bolts for flat surfaces, FC 210 is a round four-bolt flange with a raised spigot shoulder for precision centering in circular cutouts, and FL 210 is a compact oval flange with two mounting bolts for space-restricted frames.
What are the dimensions of a UC 210 bearing insert?
The standard metric UC 210 insert bearing features a 50 mm bore, a 90 mm outer diameter, and an overall inner ring width of 51.6 mm. Imperial options like the UC 210-32 feature the same 90 mm outer diameter and 51.6 mm width but accommodate a 2-inch shaft.
Are F 210 and FL 210 bearing housings interchangeable?
No, F 210 and FL 210 housings are not drop-in interchangeable. While both hold the same 50 mm UC 210 insert, F 210 uses a four-bolt square layout and FL 210 uses a two-bolt oval layout, requiring completely different bolt-hole patterns on the machine frame.
