Engineering Information Engineering Data Spherical bearings offer a greater variety of mounting positions compared to the rod end bearings. The angle of misalignment is calculated based on its mounting arrangement. Shown are three common mountings <strong>and</strong> the formulae for calculating the angle of misalignment. a2 a2 a2=Sin –1 W –Sin –1 H A A a3 a3=Sin –1 W –Sin –1 H E E Reference Letters SPHERICAL BEARINGS Series LHA Series Mounting LHB Mounting LS Arrangements LHSS Arrangements LHSSE a 2 a 3 a 4 LHSSVV a 2 a 3 a 4 -3 ±9° ±16 1/2° ±34 1/2° -2 ±8 1/2° ±13 1/2° ±28° -4 ±8° ±14 1/2° ±29° -3 ±7° ±11° ±29 1/2° -5 ±9° ±14° ±30° -4 ±9° ±13° ±30° -6 ±8° ±12 1/2° ±27° -5 ±8° ±12° ±26° -7 ±6 1/2° ±11° ±25° -6 ±7 1/2° ±10 1/2° ±23° -8 ±7 1/2° ±12 1/2° ±23° -7 ±6 1/2° ±9 1/2° ±20 1/2° -10 ±8° ±12° ±23° -8 ±7° ±10° ±20° -12 ±9° ±15° ±27° -9 ±7 1/2° ±10° ±20° -16 ±6 1/2° ±10° ±25° -10 ±7° ±9° ±19° -19 ±6° ±18 1/2° ±23 1/2° -12 ±7° ±9° ±21° -24 ±5° ±7° ±23° -14 ±7° ±9° ±16° -30 ±5° ±7° ±25° -16 ±7 1/2° ±9 1/2° ±16° P-1930-BG 04/10 Boston Gear 800-825-6544 209 a3 B – Ball Bore C – Outer Race Chamfer D – Head Diameter or Outer Race Diameter E – Ball Diameter H – Housing Width A – (D-2C) 2 + H2 W – Ball Width a4 a4 a4=Sin –1 B –Sin –1 H E E F
