              Oil Impregnated Bronze Bearings
Anchor Bronze offers oil filled sintered bronze sleeve bearings, flanged bearings and thrust bearings. Our sintered bronze products conform to ASTM recommended dimensions and tolerances. After forming, sintering and sizing, the bearings are vacuum impregnated with SAE 30 oil that provides lubricant which is metered from the bearing to the shaft during rotation. Standard sintered bronze bearings and wear plates will function satisfactorily in temperatures ranging from 10ºF to 220ºF.

Comparable specifications are :
  • ASTM Standard :      ASTM B438 Grade 1, Type 2
  • Military Standard :    MIL-B-5687D Type 1, Grade 1
  • AMS Standard :        AMS 4805
  • SAE Standard :        SAE 841 Type 1, Class A

Pressure & Velocity Ratings:

Max. PV ............. 50,000    Max. P ................. 2,000    Max. V ................. 1,200
 PV Calculation:

PV is a means of measuring the performance capabilities of bearings. P is expressed as pressure or pounds per square inch on the area of the bearing. V is velocity in feet per minute of the wear surface (surface feet per minute).

For sleeve bearings, the surface speed is .262 (pi÷12) x RPM x shaft diameter in inches. P is equal to the load on the bearing in pounds divided by the projected area in square inches. For sleeve bearings, the projected area is the length x the inside diameter of the bearing. PV is then obtained by multiplying P x V as shown in the following example:

3/4" shaft @ 341 RPM, 90 lb. total load, bearing length 1".

V = .262 x RPM x shaft diameter, or .262 x 341 x .750 = 67 sfpm.

P = total load ÷ projected area (area = .750 x 1.0 = .75 in.), or 90 lbs. ÷ .75 = 120 psi.

PV = 120 psi x 67 sfpm = 8040 PV

Piloted Driver:

For proper insertion of sintered bronze bearings

Piloted DriverSuggestions for inserting sintered bronze bearings using a piloted driver:

1. Shoulder diameter should be larger than bearing.

2. Pilot length should exceed bearing length.

3. Pilot diameter should be approximately .0003 larger than desired bearing ID after insertion.

4. Edge of housing bore should be broken to prevent shearing of bearing OD during insertion

REF:

Housing Bore - 1.2495/1.2505

Shaft Dia. - .9995/1.0000

Bearing Size - 1.003/1.004 ID x 1.253/1.254 OD.

Pilot Dia. - 1.0013 - 1.0015

Even though your available bearings may vary slightly in bore size, the proper use of a piloted driver for insertion will assure correct shaft clearance after assembly.

Depending on the bore size, bearings having dimensional differences of up to .003" can be interchanged.
