Why not?
AC motors are usually run at constant and DC motors at veriable speeds.
Simply ac or dc motor type should not have any effect on bearings & grease.
Bearing type, operating temperatures, speed, load, duty etc. determine the suitable type of grease and regreasing intervals.
Most of the times motor manufacturers give the info on motor name plate if the motor bearings require regreasing. It is adviseable to always refer to motor or bearing manufacturer recommendations.
Shell Alvania RL3 is suitable for medium size motors (with ball bearings) running at 40C ambient temperatures.

Shell Rhodina EP it is an equivalent to Shell Livona. Currently Rhodina EP out of production.

There are many possible Unix shells that users have access to. Some of these are: sh - Bourne shell (the original shell) ksh - Korn shell bash - Bourne-again shell csh - C shell tcsh - variant of the C shell and other features zsh - the 'z' shell rsh - Restricted shell ksh93 - '93 version of ksh
A shell function will do nothing unless it is explicitly called by other code, typically in a shell script. A shell script is a runnable, executable process, which can call other shell scripts and/or functions. The question might be worded backwards - it is necessary to write shell functions for shell scripts when certain logical functionality is required to be performed multiple times. Consider a shell function equivalent to a program subroutine - they operate the same way.
A basic shell program should essentially emulate a command prompt with a very limited set of commands, such as exit to close the shell and possibly cd to change the current directory. Shell's are typically used to spawn other processes, but a basic shell will typically limit which processes may be allowed to run.
An equivalent grease to Shell Alvania WR-2 would be a general-purpose lithium grease formulated for industrial applications with similar performance characteristics. Most major grease manufacturers offer a lithium-based general-purpose grease that can serve as a suitable alternative.
Your local lawn mower repair shop or auto parts store should be able to recommend a suitable grease that would be equivalent.
i am not sure
Unirex N2 is close to the equivalent of Alvania R2
SKF LGMT 2 is very similar
An equivalent to Shell Alvania 2 grease would be a general-purpose lithium-based grease with a similar consistency and application range. Some common alternatives include Mobilgrease 28, Chevron Multifak EP 2, and Exxon Centaur Moly.
An equivalent to Shell Alvania G3 grease would be a lithium-based general purpose grease with similar NLGI grade, consistency, and performance characteristics. Some alternatives could include Mobilux EP 2, Exxon Ronex MP, or Chevron SRI 2 grease.
# 00 Shell Alvania semi fluid grease
Shell Alvania RA is a lithium-based grease designed for general-purpose lubrication. It offers excellent water resistance, high load-carrying capabilities, and good mechanical stability, making it suitable for various industrial applications. This grease is commonly used in bearings, gears, and other machinery operating under moderate to high loads. Its formulation helps to ensure long-lasting performance and reliability in diverse operating conditions.
Mobilgrease XHP 222 is considered a suitable equivalent to Shell Alvania G3. Both greases are lithium-complex based and designed for high-temperature applications, providing excellent wear protection and resistance to water. Always check the technical specifications and compatibility with your specific application before substituting greases.

The Shell Oil Company grease that would be the equivalent to Mobile Polyrex EM is called Shell Albida Grease MPS. Both of them are a synthetic blend of grease used in automobiles.
